ddcac5ae09 Added a test to define INADDR_NONE if it's not present. For example, 
SunOS (solaris 2.8) does not include this define.  [Thank to Ben
Hartshorne for pointing this out.]

4c9141aac6 Removed the "ViaHeader" directive and replaced it with the 
"ViaProxyName" directive.  The "Via" HTTP header is _required_ by the
HTTP spec, so the code has been changed to always send the header.
However, including the proxy's host name could be considered a
security threat, so the "ViaProxyName" directive is used to set the
token sent in the "Via" header.  If the directive is not enabled the
proxy's host name will be used.

b081019d5a (connect_to_upstream): Fixed an off-by-one error in the snprintf() 
call used to build the URL for the upstream proxy. [Patch suggested by
David T. Pierso]

91e082671a (upstream_get): 
(upstream_add): Added support to allow ip addresses and networks to be
used when matching an upstream proxy directive.

ea50171a95 Changed the safefree() macro to make it safe to use a conditional 
statement, and also safe to use with a rvalue that has a side
effect.  [Bug fix recommended by Peter da Silva]

77ca1c8ce0 # Changed all the for calls to use the != test rather than < test. 
The change was recommended in the C/C++ User Journal magazine.

af5e1e29f6 # Changed the calls to vector_getentry() to use the new calling 
convention.
 2003-05-30 16:22:30 +00:00
Robert James Kaes
1955dcd47b (vector_getentry): Changed the API to return the data pointer and have 
the length returned in a argument variable pointer.  This should be a
more natural way of using the function.

c3eaebd1c5 # Added a vector_prepend() function and recoded the old vector_insert() 
to be a general "insert" for both vector_append() and vector_prepend()

42f9f37afc (vector_append): Renamed the vector_insert() function to more 
accurately indicate that entries are appended to the end of the
vector.

4a377a712d Improved the upstream proxy support by making the upstream proxy 
server configurable based on the destination host.  [Code written by

5e1303ecd1 (establish_http_connection): If the port being requested is not a 
standard HTTP port (80 or 443) append the port string to the host
header; otherwise, leave the host string with only the host's domain
name.

Replaced all occurrences of constant 80 and 443 with defines HTTP_PORT
and HTTP_PORT_SSL.

ac88af1f71 Fixed a bug that would kill a child process because of an invalid 
safefree() call.  Basically, destroy_conn() was trying to free memory
not allocated by malloc.  [Fix by David T. Pierson]

c94bfa8223 (build_url): Rebuild the URL from the component pieces. This function 
is used by the transparent proxy code.  [Anatole Shaw]
(process_request): Fixed up the transparent proxy code so that
filtering can be done on the whole URL.  [Anatole Shaw]

(pull_client_data): Added a bug fix for Internet Explorer (IE).  IE
will leave an extra CR and LF after the data in an HTTP POST.  The new
code will eat the extra bytes if they're present.  Thanks to Yannick
Koehler for finding the bug and offering an explanation as to why it
was happening.

Changed all calls of connptr->remote_content_length to
connptr->content_length.server

4a942bc59a # The programmer is now made to _explicitly_ enable the GDB support in 
the child handling function.

6ff4192069 Removed the remote_content_length field in the "conn" structure and 
replaced it with a smaller structure containing both the remote/server
and the local/client content-length fields if they're present in the
HTTP response headers.
 2003-04-16 16:37:59 +00:00

bcf25dc67e (add_error_variable): Test whether connptr->error_variable is NULL, 
and if so call safemalloc().  This is needed since saferealloc() will
assert() if the first argument is a NULL pointer.
 2003-04-01 16:41:33 +00:00
Robert James Kaes
7cd19206cc (establish_http_connection): Always include the port number for the 
requested server.  This fixes a problem when the server is not
listening on the default port, 80.

75dd0b22c4 Allow the URL for the statistic page to be controlled from the

  process.

Robert James Kaes
2fc9c76969 (connect_to_upstream): Reorganized the preprocessor directives to make 
sure the function's symbol name is stored, even if upstream was not
compiled it.  This should keep some compilers from reporting errors.

59ec5dc69f (strip_username_password): New function to remove any 
username/password part from the host URI.

(extract_http_url), (extract_ssl_url): Use the new
strip_username_password function to remove any non-host information
from the URI.

0a20bdd5b4 Removed the "bool_t" type since it conflicts with the newer C standards. 
The type was just replaced by "unsigned int" types.

d069b4fce9 (extract_http_url): Removed the leading "http://" from all the tests, 
since it's skipped by the caller before the URL is passed to this
function.

(process_request): Include code to handle proxy FTP requests as
well.  This also lead to a bit of a cleanup in the calling conventions
of extract_http_url function.  tinyproxy can handle both types of
resources by skipping the leading :// part.
