Revision 1.56 2002/05/12 15:34:22 jongfoster Fixing typo in a comment
Revision 1.55 2002/05/08 16:01:07 oes Optimized add_to_iob:

Revision 1.50 2002/03/12 01:45:35 oes More verbose logging
Revision 1.49 2002/03/09 20:03:52 jongfoster
Revision 1.47 2002/02/20 23:15:13 jongfoster Parsing functions now handle out-of-memory gracefully by returning an error code.
Revision 1.46 2002/01/17 21:03:47 jongfoster Moving all our URL and URL pattern parsing code to urlmatch.c.
Revision 1.45 2002/01/09 14:33:03 oes Added support for localtime_r.
Revision 1.44 2001/12/14 01:22:54 steudten Remove 'user:pass@' from 'proto://user:pass@host' for the new added header 'Host: ..'. (See Req ID 491818)
Revision 1.43 2001/11/23 00:26:38 jongfoster Fixing two really stupid errors in my previous commit
Revision 1.42 2001/11/22 21:59:30 jongfoster Adding code to handle +no-cookies-keep
Revision 1.41 2001/11/05 23:43:05 steudten Add time+date to log files.
Revision 1.40 2001/10/26 20:13:09 jongfoster ctype.h is needed in Windows, too.
Revision 1.39 2001/10/26 17:40:04 oes Introduced get_header_value() Removed http->user_agent, csp->referrer and csp->accept_types Removed client_accept()
Revision 1.38 2001/10/25 03:40:48 david__schmidt Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple threads to call select() simultaneously. So, it's time to do a real, live, native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__ (native). Both versions will work, but using __OS2__ offers multi-threading.
Revision 1.37 2001/10/23 21:36:02 jongfoster Documenting sed()'s error behaviou (doc change only)
Revision 1.36 2001/10/13 12:51:51 joergs Removed client_host, (was only required for the old 2.0.2-11 http://noijb. force-load), instead crumble Host: and add it (again) in client_host_adder (in case we get a HTTP/1.0 request without Host: header and forward it to a HTTP/1.1 server/proxy).
Revision 1.35 2001/10/09 22:39:21 jongfoster assert.h is also required under Win32, so moving out of ifndef _WIN32 block.
Revision 1.34 2001/10/07 18:50:55 oes Added server_content_encoding, renamed server_transfer_encoding
Revision 1.33 2001/10/07 18:04:49 oes Changed server_http11 to server_http and its pattern to "HTTP". Additional functionality: it now saves the HTTP status into csp->http->status and sets CT_TABOO for Status 206 (partial range)
Revision 1.32 2001/10/07 15:43:28 oes Removed FEATURE_DENY_GZIP and replaced it with client_accept_encoding, client_te and client_accept_encoding_adder, triggered by the new +no-compression action. For HTTP/1.1 the Accept-Encoding header is changed to allow only identity and chunked, and the TE header is crunched. For HTTP/1.0, Accept-Encoding is crunched.
parse_http_request no longer does anything than parsing. The rewriting of http->cmd and version mangling are gone. It now also recognizes the put and delete methods and saves the url in http->url. Removed unused variable.
renamed content_type and content_length to have the server_ prefix
server_content_type now only works if csp->content_type != CT_TABOO
added server_transfer_encoding, which
made server_http11 conditional on +downgrade action
Replaced 6 boolean members of csp with one bitmap (csp->flags)
Revision 1.31 2001/10/05 14:25:02 oes Crumble Keep-Alive from Server
Revision 1.30 2001/09/29 12:56:03 joergs IJB now changes HTTP/1.1 to HTTP/1.0 in requests and answers.
Revision 1.29 2001/09/24 21:09:24 jongfoster Fixing 2 memory leaks that Guy spotted, where the paramater to enlist() was not being free()d.
Revision 1.28 2001/09/22 16:32:28 jongfoster Removing unused includes.
Revision 1.27 2001/09/20 15:45:25 steudten
add casting from size_t to int for printf() remove local variable shadow s2
Revision 1.26 2001/09/16 17:05:14 jongfoster Removing unused include showarg.h
Revision 1.25 2001/09/16 13:21:27 jongfoster Changes to use new list functions.
Revision 1.24 2001/09/13 23:05:50 jongfoster Changing the string paramater to the header parsers a "const".
Revision 1.23 2001/09/12 18:08:19 steudten
In parse_http_request() header rewriting miss the host value, so from http://www.mydomain.com the result was just " / " not http://www.mydomain.com/ in case we forward.
Revision 1.22 2001/09/10 10:58:53 oes Silenced compiler warnings
Revision 1.21 2001/07/31 14:46:00 oes
Revision 1.18 2001/07/13 14:02:46 oes
Revision 1.16 2001/06/29 13:32:42 oes
Revision 1.14 2001/06/01 18:49:17 jongfoster Replaced "list_share" with "list" - the tiny memory gain was not worth the extra complexity.
Revision 1.13 2001/05/31 21:30:33 jongfoster Removed list code - it's now in list.[ch] Renamed "permission" to "action", and changed many features to use the actions file rather than the global config.
Revision 1.12 2001/05/31 17:33:13 oes
CRLF -> LF
Revision 1.11 2001/05/29 20:11:19 joergs '/ * inside comment' warning removed.
Revision 1.10 2001/05/29 09:50:24 jongfoster Unified blocklist/imagelist/permissionslist. File format is still under discussion, but the internal changes are (mostly) done.
Also modified interceptor behaviour:
Revision 1.8 2001/05/27 22:17:04 oes
Revision 1.6 2001/05/26 13:39:32 jongfoster Only crunches Content-Length header if applying RE filtering. Without this fix, Microsoft Windows Update wouldn't work.
Revision 1.5 2001/05/26 00:28:36 jongfoster Automatic reloading of config file. Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32). Most of the global variables have been moved to a new struct configuration_spec, accessed through csp->config->globalname Most of the globals remaining are used by the Win32 GUI.

Add content to the buffered page, expanding the buffer if necessary.

|
||||||||||||
|
Rewrite the client's Accept-Encoding header so that if doesn't allow compression, if the action applies.
Note For HTTP/1.0 the absence of the header is enough.
|
|
|
Add an Accept-Encoding header to the client's request that disables compression if the action applies, and the header is not already there. Called from `sed'. Note For HTTP/1.0, the absence of the header is enough.
|

Used in the add_client_headers list. Called from `sed'.

Handle the "from" config setting properly. Called from `sed'.

Handle the "referer" config setting properly. Called from `sed'.

|
Handle the "cookie" header properly. Called from `sed'. If cookie is accepted, add it to the cookie_list, else we crunch it. Mmmmmmmmmmm ... cookie ......

Rewrite the client's TE header so that if doesn't allow compression, if the action applies.
|

Handle "ua-" headers properly. Called from `sed'.

Handle the "user-agent" config setting properly and remember its original value to enable browser bug workarounds. Called from `sed'.

Used in the add_client_headers list. Called from `sed'.
|
|
|
Used in the add_client_headers list. Called from `sed'.
|
|
|
Adds a "Connection: close" header to csp->headers as a temporary fix for the needed but missing HTTP/1.1 support. Called from `sed'. FIXME This whole function shouldn't be neccessary!
|
|
||||||||||||
|
This is called if a header matches a pattern to "crunch".
|
|
||||||||||||
|
Write any pending "buffered" content.
|
|
|
This (odd) routine will parse the csp->iob.
|
|
||||||||||||
|
Get the value of a given header from a chained list of header lines or return NULL if no such header is present in the list.
|
|
||||||||||||||||
|
add, delete or modify lines in the HTTP header streams. On entry, it receives a linked list of headers space that was allocated dynamically (both the list nodes and the header contents). As a side effect it frees the space used by the original header lines.
|
|
||||||||||||
|
Prohibit filtering (CT_TABOO) if content encoding compresses.
|
|
||||||||||||
|
Adjust Content-Length header if we modified the body.
|
|
||||||||||||
|
Crumble any Content-MD5 headers if the document was modified. FIXME: Should we re-compute instead?
|
|
||||||||||||
|
Set the content-type for filterable types (text/.*, javascript and image/gif) unless filtering has been forbidden (CT_TABOO) while parsing earlier headers.
|
|
||||||||||||
|
Save the HTTP Status into csp->http->status Set CT_TABOO to prevent filtering if the answer is a partial range (HTTP status 206) Rewrite HTTP/1.1 answers to HTTP/1.0 if +downgrade action applies.
|
|
||||||||||||
|
Handle the server "cookie" header properly. Log cookie to the jar file. Then "crunch" it, or accept it. Called from `sed'.
|
|
||||||||||||
|
Prohibit filtering (CT_TABOO) if transfer coding compresses Raise the CSP_FLAG_CHUNKED flag if coding is "chunked" Change from "chunked" to "identity" if body was chunked but has been de-chunked for filtering.
