- * Revisions :
- * $Log: parsers.h,v $
- * Revision 1.30 2006/08/14 08:25:19 fabiankeil
- * Split filter-headers{} into filter-client-headers{}
- * and filter-server-headers{}.
- * Added parse_header_time() to share some code.
- * Replaced timegm() with mktime().
- *
- * Revision 1.29 2006/08/03 02:46:41 david__schmidt
- * Incorporate Fabian Keil's patch work:\rhttp://www.fabiankeil.de/sourcecode/privoxy/
- *
- * Revision 1.28 2006/07/18 14:48:47 david__schmidt
- * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
- * with what was really the latest development (the v_3_0_branch branch)
- *
- * Revision 1.26.2.1 2002/09/25 14:52:46 oes
- * Added basic support for OPTIONS and TRACE HTTP methods:
- * - New parser function client_max_forwards which decrements
- * the Max-Forwards HTTP header field of OPTIONS and TRACE
- * requests by one before forwarding
- * - New parser function client_host which extracts the host
- * and port information from the HTTP header field if the
- * request URI was not absolute
- * - Don't crumble and re-add the Host: header, but only generate
- * and append if missing
- *
- * Revision 1.26 2002/05/08 15:59:53 oes
- * Changed add_to_iob signature (now returns jb_err)
- *
- * Revision 1.25 2002/03/26 22:29:55 swa
- * we have a new homepage!
- *
- * Revision 1.24 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.23 2002/03/13 00:27:05 jongfoster
- * Killing warnings
- *
- * Revision 1.22 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.21 2002/03/07 03:46:17 oes
- * Fixed compiler warnings
- *
- * Revision 1.20 2002/02/20 23:15:13 jongfoster
- * Parsing functions now handle out-of-memory gracefully by returning
- * an error code.
- *
- * Revision 1.19 2002/01/17 21:03:47 jongfoster
- * Moving all our URL and URL pattern parsing code to urlmatch.c.
- *
- * Revision 1.18 2001/10/26 17:40:23 oes

- * Removed client_accept()
- *
- * Revision 1.17 2001/10/13 12:47:32 joergs
- * Removed client_host, added client_host_adder
- *
- * Revision 1.16 2001/10/07 18:50:16 oes
- * Added server_content_encoding, renamed server_transfer_encoding
- *
- * Revision 1.15 2001/10/07 18:01:55 oes
- * Changed server_http11 to server_http

- *
- * renamed content_type and content_length
- *
- * fixed client_host and strclean prototypes
- *
- * Revision 1.13 2001/09/29 12:56:03 joergs
- * IJB now changes HTTP/1.1 to HTTP/1.0 in requests and answers.
- *
- * Revision 1.12 2001/09/13 23:05:50 jongfoster
- * Changing the string paramater to the header parsers a "const".
- *
- * Revision 1.11 2001/07/31 14:46:53 oes
- * Added prototype for connection_close_adder
- *
- * Revision 1.10 2001/07/30 22:08:36 jongfoster
- * Tidying up #defines:
- * - All feature #defines are now of the form FEATURE_xxx
- * - Permanently turned off WIN_GUI_EDIT
- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.9 2001/07/29 18:43:08 jongfoster

- * ANSI C rules.
- *
- * Revision 1.8 2001/07/13 14:01:54 oes
- * Removed all #ifdef PCRS
- *
- * Revision 1.7 2001/06/29 13:32:14 oes

- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
