fb736ec3fb A _tonne_ of changes. It would almost be easier to just read the source 
itself to find out all the changes.  Changed the process_client_header()
function to use the hashmap and vector modules.  I've made this change to
better handle the Connection header.  The Connection header, it it's
present, lists all the headers which should _not_ be transmitted any
further along.  An HTTP/1.1 proxy must respect this.

Other changes are basically cosmetic.

475e526a48 Moved write_message() into sock.c because I'm using it in other places. 2001-12-24 00:01:02 +00:00

c3124815a1 Cleaned up the code which sends the "Via" header. It now uses 
write_message().

93f0406b7e Created the CHECK_CRLF() macro to handle the tests for the appropriate 
control characters in a string.

63a1fa96cc Removed duplicate code from process_server_headers() and removed the calls 
to strlen(); readline() already returns the length of the string, so use
that instead.

56b541d76b Redefined HTTP_LINE_LENGTH to be based on MAXBUFFSIZE (and set to around 
16 KB.)

Added the TUNNEL_CONFIGURED() macro to help with testing for the tunnel
support code.

Create the write_message() function to encapsulate the code which sends
the information to the file descriptor.

Moved the tunnel code into it's own function.

faf655c5db Added the code to log the request when in tunnelling mode. 2001-12-17 19:10:56 +00:00

9448787ff2 Added UPSTREAM_CONFIGURED() macro to help clean up the code. 
Ignore any blank lines when tinyproxy is expecting a request line.

Instead of sending the request line to the remote server in pieces,
tinyproxy nows sends it in once go. This was done to fix a problem with
some sites like www.heise.de.

Changed all calls to connptr->ssl to connptr->connect_method.

Changed all calls to connptr->send_message to
connptr->send_response_message.

Moved the call to Via header code to inside to the tests to handle if
tinyproxy is sending an error message (don't need to send any headers.)

a30eb425e3 #if 0'd the code handling the "Via" header in the process_client_headers() 
function since I'm not completely happy with the code.

90ee7e01ca Extract the version from the request line and store it in the conn_s 
structure.
Don't send a Connection header to the remote connection.
Handle the Via header correctly.

e61424a7bf Informing the user of the connection to the tunnel is a INFO type message, 
not a CONN level message.

d3b099140f Some code clean up due to the creation of the conns.{c,h} files which now 
store the creation/destruction and definition of the connection structure.

1bbf32f04c Fixed the problems with sending/not sending headers so that the CONNECT 
(SSL) method would work with upstream proxying!
 2001-10-25 05:12:46 +00:00
Robert James Kaes
6afa56ba09 Changed the way relay_connection() works by having the both buffers 
emptied when either socket is closed. This should be better for the tunnel
connections.
Change the connect_to_upstream() function to better utilize the
establish_http_connection() function. Code re-use is cool. :)

358b2781af Cleaned up the code in handle_connection() and added a NULL pointer test 
in the free request function.

b40e382e5a More moving around of the source code. Still can't get CONNECT to work 
with an upstream proxy.

7a613287ee Trying to allow CONNECT methods through an Upstream proxy. 2001-10-17 04:15:35 +00:00

08baf6b01b Moved the safe_read() and safe_write() functions into the sock.c file 
since they're now used in other places.

Added support for a true upstream proxy connection. This involved some
rewriting of the handle_connection() function and some of the support
functions so that they do perform the domain filtering and anonymous
filtering while still connecting to the upstream proxy. I think the code
should be cleaned up further.

b7fc58333b Removed the log messages related to memory allocation. 
Move the SSL response header into into own function.
Added support for the status host.

ea4d707d12 Finally got the SSL problem fixed. We can not send _any_ client headers 
(including the new line) to the origin server when in tunnelling mode. SSL
now works correctly. Yeah.

9c520c7a50 Changed the buffer pointer in safe_write() to be const void* since we're 
not changing the values.

Instead of building a new request and memory, simply send each part
separately. Actually uses less memory _and_ less code.

c6d2e0f7ff Massive changes. Split process_method() into a bunch of smaller files and 
changed the parsing code from REGEX and uri.c to a simplier sscanf()
method. Also, include code to handle SSL connections, but that's not quite
working yet.

malformed request to be sent.

0d421b5c39 Fixed a bug with the clientreq function which was incorrectly setting the 
clientheader flag and causing _all_ headers to be sent even in anonymous
mode.

46076808fb Fixed another NULL bug with the uri->authority. If an badly formed request 
was made in the form of http:\\www.somewhere.com/ tinyproxy would SEGV.
This has been corrected.
