tinyproxy.conf.5: explain what a site_spec looks like

if tinyproxy serves as a HTTP server (i.e. when serving stats),
use error code 401, else error code 407.

-2001-11-03  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/buffer.c (remove_from_buffer): This function is never
-	called with an empty buffer, so removed some inaccurate code which
-	would have removed an invalid line from the buffer if it was
-	empty. What was I thinking when I wrote that? Good thing is was
-	never called.
-	(add_to_buffer): Add a bit of a sanity check to make sure the
-	buffer structure hasn't been messed up some how.
-
-2001-11-02  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/acl.c (insert_acl): Tightened the check regarding whether an
-	ACL is a string or a numeric address.
-
-2001-10-25  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* Moved all the system header included into the tinyproxy.h header
-	and changed all the other files to include it. This should
-	centralise the header dependency issue into one file.
-
-	* src/conns.c: Brought back the conns.{c,h} files which contain
-	the connection structure definition plus the creation/destruction
-	routines.
-
-	* src/reqs.c (process_client_headers): Selectively send headers
-	based on whether we're using an upstream with a CONNECT
-	request. The short answer: all methods work correctly with
-	Upstream proxying and normal proxying.
-
-	* src/tinyproxy.h: Added a upstream flag to the conn_s structure
-	so we can figure out when to send headers and when not to send
-	headers. This is extremely important when trying to do upstream
-	proxying of the CONNECT method.
-
-	* src/reqs.c (relay_connection): Empty the contents of both
-	buffers when either socket is closed. This is more in line with
-	what a tunnel should do. Since either end could close with
-	information still in the buffers.
-	(connect_to_upstream): Cleaned up the code to re-use the
-	establish_http_connection() function.
-
-	* src/buffer.c (readbuff): Changed the memory allocation to 2K
-	from 48K since an Ethernet connection is usually around 1400
-	bytes. There's little point in allocating a huge amount of memory,
-	only to shrink the memory map in the next breath.
-
-2001-10-22  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/sock.c (getpeer_string): Added logging in case the
-	gethostbyaddr() function fails.
-
-	* src/reqs.c (free_request_struct): Added a test to return if the
-	pointer is NULL.
-	(handle_connection): Cleaned up the code to better handle the
-	cause where the request is NULL.
-
-	* src/sock.c (getpeer_string):
-	* src/sock.c (getpeer_ip): When the DNS lookup fails, we need to
-	initialized the user's buffer to an empty string; otherwise, the

-	Jeffrey Wheelhouse for finding this bug.
-

-
-	* src/reqs.c (connect_to_upstream): Moved the code needed to
-	rebuild the request line when using the upstream feature into it's
-	own function. Simplifies the handle_connection() function.
-
-	* src/buffer.c (readbuff): Fixed a problem where a full buffer
-	would cause the connection to be closed. Thanks to Jeffrey
-	Wheelhouse for helping me find this problem.
-
-2001-09-29  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* configure.in: Uses any CFLAGS variable passed to the configure
-	script. Also, '-g -Wall' is _not_ enabled unless debugging support
-	is compiled in. Use --enable-static to compile a statically linked
-	tinyproxy.
-
-2001-09-16  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/tinyproxy.c (main): Don't allow Tunnel and Upstream
-	directives to be both set in the configuration file.
-
-	* src/reqs.c (handle_connection): Added support for an upstream
-	proxy. What we used to use for our upstream proxy has now become a
-	TCP tunnel. The difference is that the upstream proxy will do
-	domain filtering, anonymous headers, etc. while the TCP tunnel
-	just sends the data without any processing. You can not have both
-	at the same time.
-
-	* src/utils.c (send_http_message): Instead of creating a block of
-	memory with the output message, just send it to the client. We
-	still need to process the various headers from the client, but it
-	will pick up the error when it's done talking to the proxy. Uses
-	less memory.
-
-	* src/sock.c: Moved safe_write() and safe_read() into sock.c since
-	I'm using them in more than just reqs.c.
-
-2001-09-15  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* Removed all the log_message()s which reported that memory could
-	not be allocated. There's little point in reporting a memory
-	shortage since the computer will probably crash soon anyway.
-
-	* src/reqs.c (process_request): Added the code for showing the
-	stats back into the function.
-
-	* src/tinyproxy.c (takesig): When SIGHUP is received the log file
-	is rotated instead of being truncated. The rotated log has ".rot"
-	appended to the file name.

-
-	* src/uri.c: Removed this file since it's no longer needed.
-
-	* src/reqs.c: Split the process_method() function into separate
-	smaller functions. Added support for tunnel SSL connections.
-
-	* src/tinyproxy.h: Added a field to handle SSL connections.
-
-2001-09-11  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/reqs.c (process_method): Fixed a memory leak due to the
-	change to heap allocation if there is an error.
-
-	* src/utils.c (debugging_realloc): Added the debugging version of
-	realloc().
-
-	* src/thread.c (THREAD_STACK_SIZE): Changed a threads stack size
-	to 32KB from 128KB.
-
-	* src/reqs.c (process_method):
-	* src/reqs.c (pull_client_data):
-	* src/reqs.c (process_client_headers):
-	* src/reqs.c (process_server_headers):
-	* src/buffer.c (readbuff): Using heap allocated memory for the
-	buffer rather than stack memory.
-
-	* src/uri.c (explode_uri): Fixed a potential memory leak where the
-	regular expression structure might not be freed if there was an
-	error in the expression.
-
-2001-09-08  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/ternary.c (BUFARRAY & BUFSIZE): Lowered the values to help
-	lower memory usage. A ternary tree will now max out at 4MB.
-
-	* src/utils.c: Added debugging_(malloc|calloc|free) to help track
-	down memory leaks.
-
-	* src/dnscache.c (DNS_INSERT_LIMIT): Lower the number of
-	insertions before the ternary tree is rebuilt.
-
-	* src/thread.c (thread_main): Fixed a memory leak.
-
-2001-09-07  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/thread.c (thread_pool_create): Explicitly set the detach
-	state for threads to PTHREAD_CREATE_DETACHED.
-
-	* Various error message clean up.
-
-	* src/thread.c (thread_main): Add locking around the
-	servers_waiting thread.
-
-2001-09-06  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/thread.c (thread_main): The code which closes a thread
-	doesn't actually work correct so I've moved the test to just after
-	a thread has handled a connection. The code still needs to be
-	cleaned up to handle locking.
-
-	* src/ternary.c (ternary_destroy): Fixed the deletion code as it
-	would cause a segfault if it was every called. Also, lowered the
-	sizes of the arrays for better memory usage.
-
-	* src/dnscache.c: After a certain number of insertions delete the
-	DNS cache and free the memory. The reason for this is that a
-	ternary tree doesn't lend itself to removing individual
-	entries. It's just easier (and cleaner) to simply delete the cache.
-
-2001-09-04  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/reqs.c (process_client_headers): Moved the skip header test
-	in front of the compare_header() function.
-
-	* src/ternary.c (ternary_search): Switched to doing case
-	insensitive searching.
-
-	* src/log.c (log_message): Thanks to NeilK for finding and fixing
-	a problem with the syslog code which can lead to a format string
-	attack.
-
-2001-08-30  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/dnscache.c: Removed the insert_data() function and replaced
-	the "replace" logic in dns_insert() with a call to
-	ternary_replace(). This fixes the segmentation fault problem which
-	I introduced when I "tried" to fix the memory leak. Also changed
-	the LOCKing to be around the entire dnscache() again since I still
-	need to work out how locking should be done when accessing the
-	ternary tree.
-
-	* src/ternary.c (ternary_insert_replace): Renamed ternary_insert()
-	to ternary_insert_replace() and added a extra argument. The
-	function can now "replace" data already in the tree without
-	causing a memory leak. Added two DEFINES to make coding easier:
-	ternary_insert() and ternary_replace() which both call this
-	function with the right arguments.
-
-	* src/utils.c: Removed xstrstr() since it was only used in one
-	place, and could be safely replaced with strstr. I can't even
-	remember why we had this function to begin with.
-
-	* src/reqs.c (compare_header): Removed the call to xstrstr() since
-	it's been removed from the source.
-
-2001-08-28  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/log.c (log_message): Handle a debug enabled compile better.
-
-	* src/dnscache.c (dns_insert): Fixed a memory leak if the same
-	information was inserted into the ternary tree twice.
-
-	* configure.in: Fixed the test regarding the REGEX library. Even
-	if a working REGEX was found on the system, the included REGEX was
-	being compiled in. Double Doh.
-
-	* src/log.c (log_message): Finally got the log levels worked out
-	properly. I've tested all the levels and they now produce the
-	correct output.
-
-2001-08-27  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/reqs.c (trim): Moved the trim functionality out of
-	process_request() and added a test to make sure we don't back the
-	pointer past the beginning of the string.
-
-	* src/log.c (log_message): Fixed a problem where the connect
-	messages were not getting through if the log level was set to
-	INFO.
-
-	* src/tinyproxy.h: Moved some of the includes around so that
-	tinyproxy can compile correctly on FreeBSD systems.
-
-	* src/thread.c: Added the pthread_attr_t structure since we're
-	going to be using a non-default sized stack because some OS's have
-	a stack size which is too small.
-
-	* configure.in: Added a test for detecting FreeBSD's -pthread
-	mechanism for telling GCC to use POSIX threading.
-
-	* src/utils.c (httperr): Fixed the MIME type. Should be be
-	text/html, not text/mime. Fix one bug, add two new ones. Sigh.
-
-2001-08-26  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/utils.c (httperr): Split the headers from the actual message
-	and include more headers like Date, Server, Content-Length,
-	etc. Also set the type for the error message to const char*.
-
-	* src/reqs.c (process_method): Fixed a SEGV problem if an invalid
-	request was submitted.
-
-	* Makefile.am (EXTRA_DIST): Don't include ./reconf in the
-	tarball.
-
-	* src/log.c (log_message): Fixed a problem with the new LOG_CONN
-	log level.
-
-	* configure.in: The debugging code was being included even on
-	non-debugging builds.
-
-	* src/anonymous.c (anonymous_insert): Moved the creation of the
-	search tree into the anonymous_insert() function. Therefore, the
-	search tree is _not_ created until the first insertion. This
-	should also fix a bug in main() where I was inserting headers
-	before creating the search tree. Doh.
-	(is_anonymous_enabled): Removed the tests for config.anon and
-	replaced it with a function call which returns a BOOL.
-
-	* Spell checked the ChangeLog file! :)
-
-2001-08-25  Robert James Kaes  <rjkaes@flarenet.com>
-
-	* src/thread.c (thread_main): Thanks to Hans-Georg Bork for
-	fixing a problem where the status of the threads was not
-	going back to T_WAITING if MaxRequestsPerChild was 0. Also, fixed
-	a problem with the looping system where the Debian
-	start-stop-daemon script would not stop all the threads if new
-	threads had been created.
-
-	* src/log.h (LOG_CONN): Added the LOG_CONN log level. This is less
-	verbose than LOG_INFO.
-
-	* doc/tinyproxy.8: Added the -l option to the list of command line
-	options.
-
-	* src/anonymous.c (anon_insert): Fixed a bug where anonymous
-	filtering wasn't working even if it was specified in the

-

-	These all handle reading the tinyproxy configuration file.
-
-2000-09-11 20:10  rjkaes
-
-	* src/: ternary.c, ternary.h: Generalized the ternary code which

-	used) in both anonymous and dnscache
-
-2000-09-11 20:08  rjkaes
-
-	* src/: acl.c, acl.h: Improved access control semantics. Allows
-	for a finger control for allowing and denying hosts.
-
-2000-09-11 20:07  rjkaes
-
-	* src/: thread.c, thread.h: tinyproxy now uses a pool of threads to

-	old thread, and generally managing the pool is done here.
-
-2000-09-11 20:06  rjkaes
-
-	* src/: stats.c, stats.h: This module handles the various stats
-	relating to tinyproxy's functionality.
-
-2000-09-11 20:04  rjkaes
-
-	* src/: reqs.c, reqs.h: MAJOR RE-WRITE! Read the ChangeLog and look
-	at the source. It's shorter than re-documenting the changes here. :)
-
-2000-09-11 20:03  rjkaes
-
-	* src/: tinyproxy.c, tinyproxy.h: Fixed the change user/group
-	ability.  Log when tinyproxy is using default values rather than
-	specific ones.	Cleaned up the command line arguments since
-	tinyproxy now uses a configuration file.  Removed the USR1 signal
-	and added the thread creation code.
-
-2000-09-11 20:01  rjkaes
-
-	* src/: utils.c, utils.h: Removed the xmalloc() and xstrdup()
-	functions.  Added the pidfile_create() function.  Added the OpenBSD
-	style strlcat() and strlcpy() functions.
-
-2000-09-11 19:57  rjkaes
-
-	* src/: uri.c, uri.h: Switched to the new logging style and
-	replaced the xmalloc() with straight malloc().
-
-2000-09-11 19:56  rjkaes
-
-	* src/: sock.c, sock.h: Needed locking in getpeer_string().  Added
-	mutex locking around the dnscache() call.  Removed the global
-	sockaddr and setup_fd variables.  Added the socket_blocking() and
-	socket_nonblocking() functions.  Gutted the readline() function and
-	replaced it with something similar to the 1.0 version. :)
-
-2000-09-11 19:50  rjkaes
-
-	* src/regexp.h: Moved back to the <config.h> for autoconf defines.

-
-2000-09-11 19:46  rjkaes
-
-	* src/gnuregex.c: Not using <defines.h> for autoconf anymore, so
-	move back to the <config.h> format.
-
-2000-09-11 19:43  rjkaes
-
-	* src/: filter.c, filter.h: Just using standard malloc() since the
-	xmalloc() didn't really add anything useful to the command.
-
-2000-09-11 19:42  rjkaes
-
-	* src/: dnscache.c, dnscache.h: Removed the custom hash routines.
-	Using the ternary module instead.

-	YACC files. (Also included the GNU license.)
-
-2000-09-11 19:33  rjkaes
-
-	* doc/tinyproxy.8: Since the tinyproxy program has changed, the
-	manual had to change as well.  Documents all the command line

-	FreeBSD systems.
-
-2000-03-31 17:55  rjkaes
-
-	* ChangeLog, src/reqs.c: Fixed a bug with the path in clientreq. If

-	* ChangeLog: Updated ChangeLog entry for new fix.
-

-
-	* ChangeLog: Updated to reflect changes in src/reqs.c
-
-2000-03-28 11:19  rjkaes
-
-	* src/reqs.c: Fixed a NULL pointer bug in clientreq. If the SCHEME

INSTALL

-Basic Installation
-==================
-
-   These are generic installation instructions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
-   The file `configure.in' is used to create `configure' by a program
-called `autoconf'.  You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.  If you're
-     using `csh' on an old version of System V, you might need to type
-     `sh ./configure' instead to prevent `csh' from trying to execute
-     `configure' itself.
-
-     Running `configure' takes awhile.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.
-
-  5. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  You can give `configure'
-initial values for variables by setting them in the environment.  Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
-     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
-     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
-   If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory.  After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
-   By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc.  You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on.  Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
-     CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
-   If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
-     Use and save the results of the tests in FILE instead of
-     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
-     debugging `configure'.
-
-`--help'
-     Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
-     Do not print messages saying which checks are being made.  To
-     suppress all normal output, redirect it to `/dev/null' (any error
-     messages will still be shown).
-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--version'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

- There are a few problems with this version of tinyproxy, but I'm hoping
- the benefits outweigh the negative. For some reason tinyproxy is not
- able to handle requests to *.x10.com sites. (As someone mentioned: "maybe
- this is a feature?" :) There also seem to be a few other random sites
- where tinyproxy is not communicating with the server correctly. If you
- find any such sites, let me know so I can add it to the list of domains
- where tinyproxy is failing. I'll need this information for the regression
- tests I plan on performing on the next release.
-
- As for the next release (1.5.0), I will not be adding new features.
- tinyproxy doesn't currently conform correctly to either the HTTP/1.0
- or the HTTP/1.1 standards. The goal of the 1.5 release therefore is
- to achieve standards compliance with at least HTTP/1.0. If you have
- looked at the tinyproxy code you will have noticed that all the real
- work of the proxy is performed in the reqs.c file. Therefore, other
- than bug fixes in the other files, only reqs.c should be changed in
- the 1.5.0 release. Basically, I'm hoping to just gut and replace the
- reqs.c file with a standards compliant version and release a new version.
-
- Depending on my schedule I should have the new version ready for
- pre-testing sometime next week. If you have any suggestions for improving
- tinyproxy please let me know, but I will not be incorporating them until
- 1.6 (which _hopefully_ should come out fairly quickly after 1.5 has

- DESCRIPTION
- -----------
-
- tinyproxy is a small, efficient HTTP proxy daemon.  tinyproxy is very 
- useful in a small network setting, where a larger proxy like Squid
- would either be too resource intensive, or a security risk.  One of
- the key features of tinyproxy is the buffering connection concept.
- In effect, tinyproxy will buffer a high speed response from a server, 
- and then relay it to a client at the highest speed the client will
- accept.  This feature greatly reduces the problems with sluggishness
- on the Internet.  If you are sharing an Internet connection with a
- small network, and you only want to allow HTTP requests to be
- allowed, then tinyproxy is a great tool for the network
- administrator.
-
-
- INSTALLATION
- ------------
-
- To install this package under a Unix derivative, read the INSTALL
- file.  tinyproxy uses a standard GNU configure script (basically you
- should be able to do:
-
-	 ./configure ; make ; make install
-
- in the top level directory to compile and install tinyproxy).  There
- are additional command line arguments you can supply to configure.
- They include:
-
-	--enable-debug		If you would like to turn on full
-				debugging support
-	--enable-socks		This turns on SOCKS support for using
-				tinyproxy across a fire wall.
-	--enable-xtinyproxy	Compile in support for the XTinyproxy
-				header, which is sent to any web
-				server in your domain.
-	--enable-filter		Allows tinyproxy to filter out certain
-				domains and URLs.
-	--enable-tunnel		Provides the option of having
-				tinyproxy act as TCP tunnel, rather
-				than a HTTP proxy.
-	--enable-upstream	Enable support for proxying connections
-				through another proxy server.
-	--enable-static		Compile a static version of tinyproxy
-
-
-     Options for file locations etc.
-        --with-stathost=HOST	Set the default name of the stats host
-	--with-config=FILE	Set the default location of the
-				configuration file
-
- Once you have completed your installation, if you would like to
- report your success please execute the report.sh script in the doc
- directory.  This will send an email to the authors reporting your
- version, and a few bits of information concerning the memory usage of 
- tinyproxy.  Alternatively, you could just send an email stating the
- version, whichever you prefer.
-
-
- SUPPORT
- -------
-
- If you are having problems with tinyproxy, please report the problem
- to either:
-
-	Robert James Kaes	<rjkaes@users.sourceforge.net>
-	Steven Young		<sdyoung@users.sourceforge.net>
-
- You may also wish to subscribe to the tinyproxy-user mailing list. To
- do so please visit:
-
-        http://lists.sourceforge.net/lists/listinfo/tinyproxy-users
-
- for more information on how to subscribe and post messages to the
- list.
-
- Please recompile tinyproxy with full debug support (--enable-debug)
- and include a copy of the log file, and any assert errors reported by
- tinyproxy.  Note that tinyproxy will output memory statistics to
- standard error if compiled with debugging support so you might want
- to redirect the output to a file for later examination.  Also, if you
- feel up to it, try running tinyproxy under your debugger and report
- the error your received and a context listing of the location.  Under
- gdb you would run tinyproxy like so:
-
-	 gdb tinyproxy
-
-	 (gdb) run -c location_of_tinyproxy_conf -d 2>/dev/null
-
- Now access the port tinyproxy is on until you receive a break in the
- gdb. You can now type:
-
-	 (gbd) l
-
- to produce a context listing of the location of the error.  Send a
- copy to the authors.
-
-
- HOW TO CONTRIBUTE TO tinyproxy
- ------------------------------
-
- If you would like to contribute a feature, or a bug fix to the
- tinyproxy source, please send a diff (preferable a unified
- diff. i.e. "diff -u") against the latest release of tinyproxy.  Also, 
- if you could include a brief description of what your patch does.

+# Tinyproxy
+
+Tinyproxy is a small, efficient HTTP/SSL proxy daemon released under the
+GNU General Public License.  Tinyproxy is very useful in a small network
+setting, where a larger proxy would either be too resource intensive, or
+a security risk.  One of the key features of Tinyproxy is the buffering
+connection concept.  In effect, Tinyproxy will buffer a high speed
+response from a server, and then relay it to a client at the highest
+speed the client will accept.  This feature greatly reduces the problems
+with sluggishness on the Internet.  If you are sharing an Internet
+connection with a small network, and you only want to allow HTTP
+requests to be allowed, then Tinyproxy is a great tool for the network
+administrator.
+
+For more info, please visit [the Tinyproxy web site](https://tinyproxy.github.io/).
+
+
+## Installation
+
+Tinyproxy uses a standard GNU `configure` script based on the automake
+system.  If compiling from a git checkout, you need to first run
+
+```
+./autogen.sh
+```
+
+from the top level directory to generate the `configure` script.
+The release tarball contains the pre-created `configure` script,
+so when building from a release, you can skip this step.
+Then basically all you need to do is
+
+
+```
+./configure
+make
+make install
+```
+
+in the top level directory to compile and install Tinyproxy. There are
+additional command line arguments you can supply to `configure`. They
+include:
+
+- `--enable-debug`: 
+If you would like to turn on full debugging support.
+
+- `--enable-xtinyproxy`: 
+Compile in support for the XTinyproxy header, which is sent to any
+web server in your domain.
+
+- `--enable-filter`: 
+Allows Tinyproxy to filter out certain domains and URLs.
+
+- `--enable-upstream`: 
+Enable support for proxying connections through another proxy server.
+
+- `--enable-transparent`: 
+Allow Tinyproxy to be used as a transparent proxy daemon.
+Unlike other work modes, transparent proxying doesn't require explicit
+configuration and works automatically when traffic is redirected to
+the proxy using the appropriate firewall rules.
+
+- `--enable-reverse`: 
+Enable reverse proxying.
+
+- `--with-stathost=HOST`: 
+Set the default name of the stats host.
+
+For more information about the build system, read the INSTALL file
+that is generated by `autogen.sh` and comes with the release tar ball.
+
+

+## Reporting a Vulnerability
+
+Open a public issue on github. The issue will most likely be fixed
+within a day, unless all maintainers happen to just be taking a
+vacation at the same time, which is unlikely.
+
+Even then, having the bug publicly known will allow competent people
+to come up with custom patches for distros, most likely quicker
+than black hats can craft a remote execution exploit.
+
+If you really really do not want to make the issue public, come
+to the tinyproxy IRC channel and ask for a maintainer, which you
+can then contact via private messages.
+
+Do not, however, like ["TALOS Intelligence"](https://talosintelligence.com/vulnerability_reports/TALOS-2023-1889)
+pull a random email address out of git log, then send an email
+nobody reads or responds to, and wait for 6 months for publication.
+this only gives black hats plenty time to sell, use and circulate
+zero days and get the best possible ROI.

+=head1 NAME
+
+tinyproxy.conf - Tinyproxy HTTP proxy daemon configuration file
+
+
+=head1 SYNOPSIS
+
+B<tinyproxy.conf>
+
+
+=head1 DESCRIPTION
+
+L<tinyproxy(8)> reads its configuration file, typically stored in
+`/etc/tinyproxy/tinyproxy.conf` (or passed to Tinyproxy with -c on the
+command line). This manpage describes the syntax and contents of the
+configuration file.
+
+The Tinyproxy configuration file contains key-value pairs, one per
+line. Lines starting with `#` and empty lines are comments and are
+ignored. Keywords are case-insensitive, whereas values are
+case-sensitive. Some string values must be enclosed in double
+quotes (") as noted below.
+
+The possible keywords and their descriptions are as follows:
+
+=over 4
+
+=item B<User>
+
+The user which the Tinyproxy process should run as, after the
+initial port-binding has been done as the `root` user. Either the
+user name or the UID may be specified.
+
+=item B<Group>
+
+The group which the Tinyproxy process should run as, after the
+initial port-binding has been done as the `root` user. Either the
+group name or the GID may be specified.
+
+=item B<Port>
+
+The port which the Tinyproxy service will listen on. If the port is
+less than 1024, you will need to start the Tinyproxy process as the
+`root` user.
+
+=item B<Listen>
+
+By default, Tinyproxy listens for connections on all available
+interfaces (i.e. it listens on the wildcard address `0.0.0.0`).
+With this configuration parameter, Tinyproxy can be told to listen
+only on one specific address.
+
+=item B<Bind>
+
+This allows you to specify which address Tinyproxy will bind
+to for outgoing connections.
+This parameter may be specified multiple times, then Tinyproxy
+will try all the specified addresses in order.
+
+=item B<BindSame>
+
+If this boolean parameter is set to `yes`, then Tinyproxy will
+bind the outgoing connection to the IP address of the incoming
+connection that triggered the outgoing request.
+
+=item B<Timeout>
+
+The maximum number of seconds of inactivity a connection is
+allowed to have before it is closed by Tinyproxy.
+
+=item B<ErrorFile>
+
+This parameter controls which HTML file Tinyproxy returns when a
+given HTTP error occurs. It takes two arguments, the error number
+and the location of the HTML error file. Enclose the file location
+in double quotes.
+
+=item B<DefaultErrorFile>
+
+The HTML template file returned when an error occurs for which no
+specific error file has been set. Enclose in double quotes.
+
+=item B<StatHost>
+
+The host name or IP address that is treated as the `stat host`.
+Enclose in double quotes. Whenever Tinyproxy receives a request for
+the `stat host` it returns an internal statistics page instead of
+forwarding the request to that host. The template for this page can be
+configured with the `StatFile` configuration option. The default value
+of `StatHost` is `@TINYPROXY_STATHOST@`.
+
+=item B<StatFile>
+
+The HTML file that Tinyproxy sends in response to a request for the
+`stat host`. Enclose in double quotes. If this parameter is not set,
+Tinyproxy returns a hard-coded basic statistics page. See the STATHOST
+section in the L<tinyproxy(8)> manual page for details.
+
+Note that the StatFile and the error files configured with ErrorFile
+and DefaultErrorFile are template files that can contain a few
+template variables that Tinyproxy expands prior to delivery.
+Examples are "{cause}" for an abbreviated error description and
+"{detail}" for a detailed error message.  The L<tinyproxy(8)>
+manual page contains a description of all template variables.
+
+=item B<LogFile>
+
+The location of the file to which Tinyproxy writes its debug output.
+Enclose in double quotes. Alternatively, Tinyproxy can log to syslog
+-- see the Syslog option.
+
+=item B<Syslog>
+
+When set to `On`, this option tells Tinyproxy to write its
+debug messages to syslog instead of to a log file configured
+with `LogFile`. These two options are mutually exclusive.
+
+=item B<LogLevel>
+
+Sets the log level. Messages from the set level and above are
+logged. For example, if the LogLevel was set to Warning, then all
+log messages from Warning to Critical would be output, but Notice
+and below would be suppressed. Allowed values are:
+
+=over 4
+
+=item * Critical (least verbose)
+
+=item * Error
+
+=item * Warning
+
+=item * Notice
+
+=item * Connect (log connections without Info's noise)
+
+=item * Info (most verbose)
+
+=back
+
+=item B<PidFile>
+
+The location of the file where the main Tinyproxy process stores its
+process ID for signaling purposes. Enclose in double quotes.
+
+=item B<XTinyproxy>
+
+Setting this option to `Yes` tells Tinyproxy to add a header
+`X-Tinyproxy` containing the client's IP address to the request.
+
+=item B<Upstream>
+
+This option allows you to set up a set of rules for deciding
+whether an upstream proxy server is to be used, based on the
+host or domain of the site being accessed. The rules are stored
+in the order encountered in the configuration file and the
+LAST matching rule wins. The following forms for specifying upstream
+rules exist:
+
+=over 4
+
+=item * I<upstream type host:port> turns proxy upstream support on generally.
+
+=item * I<upstream type user:pass@host:port>
+does the same, but uses the supplied credentials for authentication.
+
+=item * I<upstream type host:port "site_spec">
+turns on the upstream proxy for the sites matching `site_spec`.
+
+`type` can be one of `http`, `socks4`, `socks5`, `none`.
+
+a `site_spec` is either a full domain name, a domain name starting with a
+`.`, in which case it is treated as a suffix, or an ip/mask tuple.
+the `site_spec` needs to be double-quoted.
+
+=item * I<upstream none "site_spec">
+turns off upstream support for sites matching `site_spec`, that means the
+connection is done directly.
+
+=back
+
+It's recommended to use raw IP addresses to specify the upstream host, so
+no costly DNS lookup has to be done everytime it is used.
+IPv6 addresses need to be enclosed in square brackets.
+
+The site can be specified in various forms as a hostname, domain
+name or as an IP range:
+
+=over 4
+
+=item * I<name>     matches host exactly
+
+=item * I<.name>    matches any host in domain "name"
+
+=item * I<.>        matches any host with no domain (in 'empty' domain)
+
+=item * I<IP/bits>  matches network/mask
+
+=item * I<IP/mask>  matches network/mask
+
+=back
+
+Note that the upstream directive can also be used to null-route
+a specific target domain/host, e.g.:
+`upstream http 0.0.0.0:0 ".adserver.com"`
+
+=item B<MaxClients>
+
+Tinyproxy creates one thread for each connected client.
+This options specifies the absolute highest number processes that
+will be created. With other words, only MaxClients clients can be
+connected to Tinyproxy simultaneously.
+
+=item B<Allow>
+
+=item B<Deny>
+
+The `Allow` and `Deny` options provide a means to customize
+which clients are allowed to access Tinyproxy. `Allow` and `Deny`
+lines can be specified multiple times to build the access control
+list for Tinyproxy. The order in the config file is important.
+If there are no `Allow` or `Deny` lines, then all clients are
+allowed. Otherwise, the default action is to deny access.
+The argument to `Allow` or `Deny` can be a single IP address
+of a client host, like `127.0.0.1`, an IP address range, like
+`192.168.0.1/24` or a string that will be matched against the
+end of the client host name, i.e, this can be a full host name
+like `host.example.com` or a domain name like `.example.com` or
+even a top level domain name like `.com`.
+Note that by adding a rule using a host or domain name, a costly name
+lookup has to be done for every new connection, which could slow down
+the service considerably.
+
+=item B<BasicAuth>
+
+Configure HTTP "Basic Authentication" username and password
+for accessing the proxy.  If there are any entries specified,
+access is only granted for authenticated users.
+
+    BasicAuth user password
+
+=item B<BasicAuthRealm>
+
+In case "BasicAuth" is configured, the "realm" information.
+"Proxy Authentication Required" status http 407 "error-response" can be
+customized.
+
+- defaults in code to "Tinyproxy" (PACKAGE_NAME), if not configured.
+
+=item B<AddHeader>
+
+Configure one or more HTTP request headers to be added to outgoing
+HTTP requests that Tinyproxy makes. Note that this option will not
+work for HTTPS traffic, as Tinyproxy has no control over what
+headers are exchanged.
+
+    AddHeader "X-My-Header" "Powered by Tinyproxy"
+
+=item B<ViaProxyName>
+
+RFC 2616 requires proxies to add a `Via` header to the HTTP
+requests, but using the real host name can be a security
+concern. If the `ViaProxyname` option is present, then its
+string value will be used as the host name in the Via header.
+Otherwise, the server's host name will be used. Enclose in double
+quotes.
+
+=item B<DisableViaHeader>
+
+When this is set to yes, Tinyproxy does NOT add the `Via` header
+to the requests. This virtually puts Tinyproxy into stealth mode.
+Note that RFC 2616 requires proxies to set the `Via` header, so by
+enabling this option, you break compliance.
+Don't disable the `Via` header unless you know what you are doing...
+
+=item B<Filter>
+
+Tinyproxy supports filtering of web sites based on URLs or
+domains. This option specifies the location of the file
+containing the filter rules, one rule per line.
+
+Rules are specified as POSIX basic regular expressions (BRE), unless
+another FilterType is specified.
+Comment lines start with a `#` character.
+
+Example filter file contents:
+
+ # filter exactly cnn.com
+ ^cnn\.com$
+ 
+ # filter all subdomains of cnn.com, but not cnn.com itself
+ .*\.cnn.com$
+ 
+ # filter any domain that has cnn.com in it, like xcnn.comfy.org
+ cnn\.com
+ 
+ # filter any domain that ends in cnn.com
+ cnn\.com$
+ 
+ # filter any domain that starts with adserver
+ ^adserver
+
+=item B<FilterType>
+
+This option can be set to one of `bre`, `ere`, or `fnmatch`.
+If `bre` is set, the rules specified in the filter file are matched
+using POSIX basic regular expressions, when set to `ere`, using
+POSIX extended regular expressions, and when set to `fnmatch` using
+the `fnmatch` function as specified in the manpage `man 3p fnmatch`.
+`fnmatch` matching is identical to what's used in the shell to match
+filenames, so for example `*.google.com` matches everything that
+ends with `.google.com`.
+If you don't know what regular expressions are or you're using filter
+lists from 3rd party sources, `fnmatch` is probably what you want.
+It's also the fastest matching method of the three.
+
+=item B<FilterURLs>
+
+If this boolean option is set to `Yes` or `On`, filtering is
+performed for URLs rather than for domains. The default is to
+filter based on domains.
+
+Note that filtering for URLs works only in plain HTTP scenarios.
+Since HTTPS has become ubiquitous during the last years, this
+will only work on a tiny fraction of websites, so it is
+recommended not to use this option.
+
+=item B<FilterExtended>
+
+Deprecated. Use `FilterType ere` instead.
+If this boolean option is set to `Yes`, then extended POSIX
+regular expressions are used for matching the filter rules.
+The default is to use basic POSIX regular expressions.
+
+=item B<FilterCaseSensitive>
+
+If this boolean option is set to `Yes`, then the filter rules
+are matched in a case sensitive manner. The default is to
+match case-insensitively, unfortunately.
+If you set this to `Yes`, then your matching will be almost
+twice as fast.
+This setting affects only `bre` and `ere` FilterTypes, fnmatch
+is always case sensitive.
+
+=item B<FilterDefaultDeny>
+
+The default filtering policy is to allow everything that is
+not matched by a filtering rule. Setting `FilterDefaultDeny`
+to `Yes` changes the policy do deny everything but the domains
+or URLs matched by the filtering rules.
+In other words, if set to `No` the Filter list acts as a
+blacklist, if set to `Yes` as a whitelist.
+
+=item B<Anonymous>
+
+If an `Anonymous` keyword is present, then anonymous proxying
+is enabled.  The headers listed with `Anonymous` are allowed
+through, while all others are denied. If no Anonymous keyword
+is present, then all headers are allowed through.  You must
+include double quotes around the headers.
+
+Most sites require cookies to be enabled for them to work correctly, so
+you will need to allow cookies through if you access those sites.
+
+Example:
+
+    Anonymous "Host"
+    Anonymous "Authorization"
+    Anonymous "Cookie"
+
+=item B<ConnectPort>
+
+This option can be used to specify the ports allowed for the
+CONNECT method. If no `ConnectPort` line is found, then all
+ports are allowed. To disable CONNECT altogether, include a
+single ConnectPort line with a value of `0`.
+
+=item B<ReversePath>
+
+Configure one or more ReversePath directives to enable reverse proxy
+support. With reverse proxying it's possible to make a number of
+sites appear as if they were part of a single site.
+
+If you uncomment the following two directives and run Tinyproxy
+on your own computer at port 8888, you can access example.com,
+using http://localhost:8888/example/.
+
+    ReversePath "/example/" "http://www.example.com/"
+
+=item B<ReverseOnly>
+
+When using Tinyproxy as a reverse proxy, it is STRONGLY
+recommended that the normal proxy is turned off by setting
+this boolean option to `Yes`.
+
+=item B<ReverseMagic>
+
+Setting this option to `Yes`, makes Tinyproxy use a cookie to
+track reverse proxy mappings. If you need to reverse proxy
+sites which have absolute links you must use this option.
+
+=item B<ReverseBaseURL>
+
+The URL that is used to access this reverse proxy. The URL is
+used to rewrite HTTP redirects so that they won't escape the
+proxy. If you have a chain of reverse proxies, you'll need to
+put the outermost URL here (the address which the end user
+types into his/her browser).  If this option is not set then
+no rewriting of redirects occurs.

+=head1 NAME
+
+tinyproxy - A light-weight HTTP proxy daemon
+
+
+=head1 SYNOPSIS
+
+B<tinyproxy> [-vdch]
+
+
+=head1 DESCRIPTION
+
+B<tinyproxy> is a light-weight HTTP proxy daemon designed to consume a
+minimum amount of system resources. It listens on a given TCP port and
+handles HTTP proxy requests. Designed from the ground up to be fast and
+yet small, it is an ideal solution for use cases such as embedded
+deployments where a full featured HTTP proxy is required, but the system
+resources for a larger proxy are unavailable.
+
+
+=head1 OPTIONS
+
+B<tinyproxy> accepts the following options:
+
+=over 4
+
+=item B<-c <config-file>>
+
+Use an alternate configuration file.
+
+=item B<-d>
+
+Don't daemonize and stay in the foreground. Useful for debugging purposes.

+=item B<-h>
+
+Display a short help screen of command line arguments and exit.
+
+=item B<-v>
+
+Display version information and exit.
+
+=back
+
+=head1 SIGNALS
+
+In addition to command-line options, there are also several signals that
+can be sent to B<tinyproxy> while it is running to generate debugging
+information and to force certain events.
+
+=over 4
+
+=item B<SIGHUP>
+
+Force Tinyproxy to do a garbage collection on the current
+connections linked list. This is usually done automatically after a
+certain number of connections have been handled.
+(Daemon mode only)
+
+=item B<SIGUSR1>
+
+Force reload of config file and filter list.
+This is handy to update the configuration if Tinyproxy is running
+in foreground without dropping active connections.
+
+=back
+
+=head1 TEMPLATE FILES
+
+There are two occasions when Tinyproxy delivers HTML pages to
+the client on it's own right:
+
+=over 4
+
+=item * When an error occurred, a corresponding error page is returned.
+
+=item * When a request for the stathost is made, a page summarizing the
+connection statistics is returned. (See STATHOST below.)
+
+=back
+
+The layout of both error pages and the statistics page can be
+controlled via configurable HTML template files that are plain
+HTML files that additionally understand a few template
+variables.
+
+
+=head1 TEMPLATE VARIABLES
+
+There are several standard HTML variables that are available in every
+template file:
+
+=over 4
+
+=item B<request>
+
+The full HTTP request line.
+
+=item B<cause>
+
+The abbreviated cause of the error condition.
+
+=item B<clientip>
+
+The IP address of the client making the request.
+
+=item B<clienthost>
+
+The hostname of the client making the request.
+
+=item B<version>
+
+The version of Tinyproxy.
+
+=item B<package>
+
+The package name. Presently, resolves to 'tinyproxy'.
+
+=item B<date>
+
+The current date/time in HTTP format.
+
+=back
+
+In addition, almost all templates support:
+
+=over 4
+
+=item B<detail>
+
+A detailed, plain English explanation of the error and possible
+causes.
+
+=back
+
+When Tinyproxy finds a variable name enclosed in braces, e.g.
+"{request}", then this is replaced by the value of the corresponding
+variable before delivery of the page.
+
+
+=head1 STATHOST
+
+Tinyproxy returns a HTML page with connection statistics when it
+receives a HTTP request for a certain host -- the stathost.  The
+stathost name defaults to `@TINYPROXY_STATHOST@` and can be changed at
+runtime to any name or IP address with the configuration variable
+`StatHost`.
+
+The stat file template can be changed at runtime through the
+configuration variable `StatFile`.

+<a id="tinyproxy" class="anchor" href="#tinyproxy" aria-hidden="true"><span class="octicon octicon-link"></span></a>Tinyproxy</h1>
+
+<p>Tinyproxy is a light-weight HTTP/HTTPS proxy daemon for POSIX operating systems. Designed from the ground up to be fast and yet small, it is an ideal solution for use cases such as embedded deployments where a full featured HTTP proxy is required, but the system resources for a larger proxy are unavailable.</p>
+
+<p>Tinyproxy is distributed using the GNU GPL license (version 2 or above).</p>
+
+<h2>
+<a id="features" class="anchor" href="#features" aria-hidden="true"><span class="octicon octicon-link"></span></a>Features</h2>
+
+<p>Tinyproxy has a <strong>small footprint</strong> and requires very little in the way of system resources. The memory footprint tends to be around 2 MB with glibc, and the CPU load increases linearly with the number of simultaneous connections (depending on the speed of the connection). Thus, Tinyproxy can be run on an older machine, or on a network appliance such as a Linux-based broadband router, without any noticeable impact on performance.</p>
+
+<p>Tinyproxy requires only a <strong>minimal POSIX environment</strong> to build and operate. It can use additional libraries to add functionality though.</p>
+
+<p>Tinyproxy allows forwarding of <strong>HTTPS connections</strong> without modifying traffic in any way through the <code>CONNECT</code> method (see the <code>ConnectPort</code> directive, which you should disable, unless you want to restrict the users).</p>
+
+<p>Tinyproxy supports being configured as a <strong>transparent proxy</strong>, so that a proxy can be used without requiring any client-side configuration. You can also use it as a <strong>reverse proxy</strong> front-end to your websites.</p>
+
+<p>Using the <code>AddHeader</code> directive, you can <strong>add/insert HTTP headers</strong> to outgoing traffic (HTTP only).</p>
+
+<p>If you're looking to build a custom web proxy, Tinyproxy is <strong>easy to modify</strong> to your custom needs. The source is straightforward, adhering to the KISS principle. As such, it can be used as a foundation for anything you may need a web proxy to do.</p>
+
+<p>Tinyproxy has <strong>privacy features</strong> which can let you configure which HTTP headers should be allowed through, and which should be blocked. This allows you to restrict both what data comes to your web browser from the HTTP server (e.g., cookies), and to restrict what data is allowed through from your web browser to the HTTP server (e.g., version information). Note that these features do not affect HTTPS connections.</p>
+
+<p>Using the <strong>remote monitoring</strong> facility, you can access proxy statistics from afar, letting you know exactly how busy the proxy is.</p>
+
+<p>You can configure Tinyproxy to <strong>control access</strong> by only allowing requests from a certain subnet, or from a certain interface, thus ensuring that random, unauthorized people will not be using your proxy.</p>
+
+<p>With a bit of configuration (specifically, making Tinyproxy created files owned by a non-root user and running it on a port greater than 1024), Tinyproxy can be made to run without any special privileges, thus minimizing the chance of system compromise. In fact, it is <b>recommended</b> to run it as a regular/restricted user. Furthermore, it was designed with an eye towards preventing buffer overflows. The simplicity of the code ensures it remains easy to spot such bugs.</p>
+
+<h2>
+<a id="downloads" class="anchor" href="#downloads" aria-hidden="true"><span class="octicon octicon-link"></span></a>Downloads</h2>
+
+<p>Note that many distributions ship horribly outdated versions of tinyproxy, therefore it is recommended to compile it from source.</p>
+
+<ul>
+<li>On Red Hat Enterprise Linux, or its derivatives such as CentOS, install Tinyproxy from the EPEL repository by running yum install tinyproxy.</li>
+<li>On Fedora, install Tinyproxy by running yum install tinyproxy.</li>
+<li>On Debian and derived distributions, run apt-get install tinyproxy to install Tinyproxy.</li>
+<li>For openSUSE run: zypper in tinyproxy</li>
+<li>Arch users can install the Tinyproxy package from the community repository. Run pacman -S tinyproxy to install it.</li>
+<li>FreeBSD, OpenBSD or NetBSD users can use the pkg_add utility to install the tinyproxy package.</li>
+<li>Mac OS X users can check MacPorts to see if the Tinyproxy port there is recent enough.</li>
+</ul>
+
+<p>If you feel that the Tinyproxy binary package in your operating system is not recent (likely), please contact the package maintainer for that particular operating system. If this fails, you can always compile the latest stable, or even better, the latest git master version, from source code.</p>
+
+<p>We distribute Tinyproxy in source code form, and it has to be compiled in order to be used on your system. Please see the INSTALL file in the source code tree for build instructions. The current stable version of Tinyproxy is available on the <a href="https://github.com/tinyproxy/tinyproxy/releases">releases page</a>. The Tinyproxy NEWS file contains the release notes. You can verify the tarball using its PGP signature. You can also browse the older releases of Tinyproxy.</p>
+
+<p>We use Git as the version control system for the Tinyproxy source code repository. To get a copy of the Tinyproxy repository, use the command:</p>
+
+<p>git clone <a href="https://github.com/tinyproxy/tinyproxy.git">https://github.com/tinyproxy/tinyproxy.git</a></p>
+
+<h2>
+<a id="quickstart" class="anchor" href="#quickstart" aria-hidden="true"><span class="octicon octicon-link"></span></a>Quickstart</h2>
+
+<p>The quickest way to get started is using a minimal config file like the below:</p>
+
+<pre><code>
+Port 8888
+Listen 127.0.0.1
+Timeout 600
+Allow 127.0.0.1
+</code></pre>
+
+<p>And then simply run <code>tinyproxy -d -c tinyproxy.conf</code> as your current user. This starts tinyproxy in foreground mode with <code>tinyproxy.conf</code> as its config, while logging to stdout. Now, all programs supporting a HTTP proxy can use 127.0.0.1:8888 as a proxy. You can try it out using <code>http_proxy=127.0.0.1:8888 curl example.com</code>.</p>

+## tinyproxy.conf -- tinyproxy daemon configuration file
+##
+## This example tinyproxy.conf file contains example settings
+## with explanations in comments. For decriptions of all
+## parameters, see the tinyproxy.conf(5) manual page.
+##
+
+#
+# User/Group: This allows you to set the user and group that will be
+# used for tinyproxy after the initial binding to the port has been done
+# as the root user. Either the user or group name or the UID or GID
+# number may be used.
+#
+User nobody
+Group nobody
+
+#
+# Port: Specify the port which tinyproxy will listen on.  Please note
+# that should you choose to run on a port lower than 1024 you will need
+# to start tinyproxy using root.
+#
+Port 8888
+
+#
+# Listen: If you have multiple interfaces this allows you to bind to
+# only one. If this is commented out, tinyproxy will bind to all
+# interfaces present.
+#
+#Listen 192.168.0.1
+
+#
+# Bind: This allows you to specify which interface will be used for
+# outgoing connections.  This is useful for multi-home'd machines where
+# you want all traffic to appear outgoing from one particular interface.
+#
+#Bind 192.168.0.1
+
+#
+# BindSame: If enabled, tinyproxy will bind the outgoing connection to the
+# ip address of the incoming connection.
+#
+#BindSame yes
+
+#
+# Timeout: The maximum number of seconds of inactivity a connection is
+# allowed to have before it is closed by tinyproxy.
+#
+Timeout 600
+
+#
+# ErrorFile: Defines the HTML file to send when a given HTTP error
+# occurs.  You will probably need to customize the location to your
+# particular install.  The usual locations to check are:
+#   /usr/local/share/tinyproxy
+#   /usr/share/tinyproxy
+#   /etc/tinyproxy
+#
+#ErrorFile 400 "@pkgdatadir@/400.html"
+#ErrorFile 502 "@pkgdatadir@/502.html"
+#ErrorFile 503 "@pkgdatadir@/503.html"
+#ErrorFile 403 "@pkgdatadir@/403.html"
+#ErrorFile 408 "@pkgdatadir@/408.html"
+
+#
+# DefaultErrorFile: The HTML file that gets sent if there is no
+# HTML file defined with an ErrorFile keyword for the HTTP error
+# that has occured.
+#
+DefaultErrorFile "@pkgdatadir@/default.html"
+
+#
+# StatHost: This configures the host name or IP address that is treated
+# as the stat host: Whenever a request for this host is received,
+# Tinyproxy will return an internal statistics page instead of
+# forwarding the request to that host.  The default value of StatHost is
+# @TINYPROXY_STATHOST@.
+#
+#StatHost "@TINYPROXY_STATHOST@"
+#
+
+#
+# StatFile: The HTML file that gets sent when a request is made
+# for the stathost.  If this file doesn't exist a basic page is
+# hardcoded in tinyproxy.
+#
+StatFile "@pkgdatadir@/stats.html"
+
+#
+# LogFile: Allows you to specify the location where information should
+# be logged to.  If you would prefer to log to syslog, then disable this
+# and enable the Syslog directive.  These directives are mutually
+# exclusive. If neither Syslog nor LogFile are specified, output goes
+# to stdout.
+#
+#LogFile "@localstatedir@/log/tinyproxy/tinyproxy.log"
+
+#
+# Syslog: Tell tinyproxy to use syslog instead of a logfile.  This
+# option must not be enabled if the Logfile directive is being used.
+# These two directives are mutually exclusive.
+#
+#Syslog On
+
+#
+# LogLevel: Warning
+#
+# Set the logging level. Allowed settings are:
+#	Critical	(least verbose)
+#	Error
+#	Warning
+#	Notice
+#	Connect		(to log connections without Info's noise)
+#	Info		(most verbose)
+#
+# The LogLevel logs from the set level and above. For example, if the
+# LogLevel was set to Warning, then all log messages from Warning to
+# Critical would be output, but Notice and below would be suppressed.
+#
+LogLevel Info
+
+#
+# PidFile: Write the PID of the main tinyproxy thread to this file so it
+# can be used for signalling purposes.
+# If not specified, no pidfile will be written.
+#
+#PidFile "@runstatedir@/tinyproxy/tinyproxy.pid"
+
+#
+# XTinyproxy: Tell Tinyproxy to include the X-Tinyproxy header, which
+# contains the client's IP address.
+#
+#XTinyproxy Yes
+
+#
+# Upstream:
+#
+# Turns on upstream proxy support.
+#
+# The upstream rules allow you to selectively route upstream connections
+# based on the host/domain of the site being accessed.
+#
+# Syntax: upstream type (user:pass@)ip:port ("domain")
+# Or:     upstream none "domain"
+# The parts in parens are optional.
+# Possible types are http, socks4, socks5, none
+#
+# For example:
+#  # connection to test domain goes through testproxy
+#  upstream http testproxy:8008 ".test.domain.invalid"
+#  upstream http testproxy:8008 ".our_testbed.example.com"
+#  upstream http testproxy:8008 "192.168.128.0/255.255.254.0"
+#
+#  # upstream proxy using basic authentication
+#  upstream http user:pass@testproxy:8008 ".test.domain.invalid"
+#
+#  # no upstream proxy for internal websites and unqualified hosts
+#  upstream none ".internal.example.com"
+#  upstream none "www.example.com"
+#  upstream none "10.0.0.0/8"
+#  upstream none "192.168.0.0/255.255.254.0"
+#  upstream none "."
+#
+#  # connection to these boxes go through their DMZ firewalls
+#  upstream http cust1_firewall:8008 "testbed_for_cust1"
+#  upstream http cust2_firewall:8008 "testbed_for_cust2"
+#
+#  # default upstream is internet firewall
+#  upstream http firewall.internal.example.com:80
+#
+# You may also use SOCKS4/SOCKS5 upstream proxies:
+#  upstream socks4 127.0.0.1:9050
+#  upstream socks5 socksproxy:1080
+#
+# The LAST matching rule wins the route decision.  As you can see, you
+# can use a host, or a domain:
+#  name     matches host exactly
+#  .name    matches any host in domain "name"
+#  .        matches any host with no domain (in 'empty' domain)
+#  IP/bits  matches network/mask
+#  IP/mask  matches network/mask
+#
+#Upstream http some.remote.proxy:port
+
+#
+# MaxClients: This is the absolute highest number of threads which will
+# be created. In other words, only MaxClients number of clients can be
+# connected at the same time.
+#
+MaxClients 100
+
+#
+# Allow: Customization of authorization controls. If there are any
+# access control keywords then the default action is to DENY. Otherwise,
+# the default action is ALLOW.
+#
+# The order of the controls are important. All incoming connections are
+# tested against the controls based on order.
+#
+Allow 127.0.0.1
+Allow ::1
+
+# BasicAuth: HTTP "Basic Authentication" for accessing the proxy.
+# If there are any entries specified, access is only granted for authenticated
+# users.
+#BasicAuth user password
+
+# BasicAuthRealm : In case BasicAuth is configured, the "realm" information.
+# "Proxy Authentication Required" status http 407 "error-response" can be
+# customized.
+#
+# - defaults in code to "Tinyproxy" (PACKAGE_NAME), if not configured.
+#BasicAuthRealm "Tinyproxy"
+
+#
+# AddHeader: Adds the specified headers to outgoing HTTP requests that
+# Tinyproxy makes. Note that this option will not work for HTTPS
+# traffic, as Tinyproxy has no control over what headers are exchanged.
+#
+#AddHeader "X-My-Header" "Powered by Tinyproxy"
+
+#
+# ViaProxyName: The "Via" header is required by the HTTP RFC, but using
+# the real host name is a security concern.  If the following directive
+# is enabled, the string supplied will be used as the host name in the
+# Via header; otherwise, the server's host name will be used.
+#
+ViaProxyName "tinyproxy"
+
+#
+# DisableViaHeader: When this is set to yes, Tinyproxy does NOT add
+# the Via header to the requests. This virtually puts Tinyproxy into
+# stealth mode. Note that RFC 2616 requires proxies to set the Via
+# header, so by enabling this option, you break compliance.
+# Don't disable the Via header unless you know what you are doing...
+#
+#DisableViaHeader Yes
+
+#
+# Filter: This allows you to specify the location of the filter file.
+#
+#Filter "@pkgsysconfdir@/filter"
+
+#
+# FilterURLs: Filter based on URLs rather than domains.
+#
+#FilterURLs On
+
+#
+# FilterType: Use bre (default), ere, or fnmatch for filtering.
+#
+#FilterType fnmatch
+
+#
+# FilterCaseSensitive: Use case sensitive regular expressions.
+#
+#FilterCaseSensitive On
+
+#
+# FilterDefaultDeny: Change the default policy of the filtering system.
+# If this directive is commented out, or is set to "No" then the default
+# policy is to allow everything which is not specifically denied by the
+# filter file.
+#
+# However, by setting this directive to "Yes" the default policy becomes
+# to deny everything which is _not_ specifically allowed by the filter
+# file.
+#
+#FilterDefaultDeny Yes
+
+#
+# Anonymous: If an Anonymous keyword is present, then anonymous proxying
+# is enabled.  The headers listed are allowed through, while all others
+# are denied. If no Anonymous keyword is present, then all headers are
+# allowed through.  You must include quotes around the headers.
+#
+# Most sites require cookies to be enabled for them to work correctly, so
+# you will need to allow Cookies through if you access those sites.
+#
+#Anonymous "Host"
+#Anonymous "Authorization"
+#Anonymous "Cookie"
+
+#
+# ConnectPort: This is a list of ports allowed by tinyproxy when the
+# CONNECT method is used.  To disable the CONNECT method altogether, set
+# the value to 0.  If no ConnectPort line is found, all ports are
+# allowed.
+#
+# The following two ports are used by SSL.
+#
+#ConnectPort 443
+#ConnectPort 563
+
+#
+# Configure one or more ReversePath directives to enable reverse proxy
+# support. With reverse proxying it's possible to make a number of
+# sites appear as if they were part of a single site.
+#
+# If you uncomment the following two directives and run tinyproxy
+# on your own computer at port 8888, you can access Google using
+# http://localhost:8888/google/ and Wired News using
+# http://localhost:8888/wired/news/. Neither will actually work
+# until you uncomment ReverseMagic as they use absolute linking.
+#
+#ReversePath "/google/"	"http://www.google.com/"
+#ReversePath "/wired/"	"http://www.wired.com/"
+
+#
+# When using tinyproxy as a reverse proxy, it is STRONGLY recommended
+# that the normal proxy is turned off by uncommenting the next directive.
+#
+#ReverseOnly Yes
+
+#
+# Use a cookie to track reverse proxy mappings. If you need to reverse
+# proxy sites which have absolute links you must uncomment this.
+#
+#ReverseMagic Yes
+
+#
+# The URL that's used to access this reverse proxy. The URL is used to
+# rewrite HTTP redirects so that they won't escape the proxy. If you
+# have a chain of reverse proxies, you'll need to put the outermost
+# URL here (the address which the end user types into his/her browser).
+#
+# If not set then no rewriting occurs.
+#
+#ReverseBaseURL "http://localhost:8888/"

+ * ----------------
+ * The idea behind this application programming interface (API) is to
+ * represent an HTTP response message as a concrete entity.  The API
+ * functions allow the message to be built up systematically before
+ * transmission to a connected socket.
+ *
+ * The order of the functions in your program would look something like
+ * this:
+ *   http_message_create()
+ *   http_message_set_response()
+ *   http_message_set_body() [optional if no body is required]
+ *   http_message_add_headers() [optional if no additional headers are used]
+ *   http_message_send()
+ *   http_message_destroy()
+ *
+ * NOTE: No user data is stored in the http_message_t type; therefore,
+ * do not delete strings referenced by the http_message_t object
+ * before you call http_message_destroy().  By not copying data, the
+ * API functions are faster, but you must take greater care.
+ *
+ * (Side note: be _very_ careful when using stack allocated memory with
+ * this API.  Bad things will happen if you try to pass the
+ * http_message_t out of the calling function since the stack
+ * allocated memory referenced by the http_message_t will no long
+ * exist.)
