*
* File : $Source: /cvsroot/ijbswa/current/parsers.h,v $
*
* Revisions :
* $Log: parsers.h,v $
+ * Revision 1.48 2008/05/30 15:57:23 fabiankeil
+ * Remove now-useless reference to debug.
+ *
+ * Revision 1.47 2008/05/21 20:12:11 fabiankeil
+ * The whole point of strclean() is to modify the
+ * first parameter, so don't mark it immutable,
+ * even though the compiler lets us get away with it.
+ *
+ * Revision 1.46 2008/05/21 15:47:14 fabiankeil
+ * Streamline sed()'s prototype and declare
+ * the header parse and add structures static.
+ *
+ * Revision 1.45 2008/05/20 20:13:30 fabiankeil
+ * Factor update_server_headers() out of sed(), ditch the
+ * first_run hack and make server_patterns_light static.
+ *
+ * Revision 1.44 2008/05/20 16:05:09 fabiankeil
+ * Move parsers structure definition from project.h to parsers.h.
+ *
+ * Revision 1.43 2008/05/10 13:23:38 fabiankeil
+ * Don't provide get_header() with the whole client state
+ * structure when it only needs access to csp->iob.
+ *
+ * Revision 1.42 2008/04/17 14:40:49 fabiankeil
+ * Provide get_http_time() with the buffer size so it doesn't
+ * have to blindly assume that the buffer is big enough.
+ *
+ * Revision 1.41 2008/04/16 16:38:21 fabiankeil
+ * Don't pass the whole csp structure to flush_socket()
+ * when it only needs a file descriptor and a buffer.
+ *
+ * Revision 1.40 2007/08/11 14:47:26 fabiankeil
+ * Remove the prototypes for functions that are only
+ * used in parsers.c and thus should be static.
+ *
+ * Revision 1.39 2007/06/01 16:31:55 fabiankeil
+ * Change sed() to return a jb_err in preparation for forward-override{}.
+ *
+ * Revision 1.38 2007/03/25 14:27:11 fabiankeil
+ * Let parse_header_time() return a jb_err code
+ * instead of a pointer that can only be used to
+ * check for NULL anyway.
+ *
+ * Revision 1.37 2007/03/20 15:22:17 fabiankeil
+ * - Remove filter_client_header() and filter_client_header(),
+ * filter_header() now checks the shiny new
+ * CSP_FLAG_CLIENT_HEADER_PARSING_DONE flag instead.
+ *
+ * Revision 1.36 2007/03/05 13:25:32 fabiankeil
+ * - Cosmetical changes for LOG_LEVEL_RE_FILTER messages.
+ * - Handle "Cookie:" and "Connection:" headers a bit smarter
+ * (don't crunch them just to recreate them later on).
+ * - Add another non-standard time format for the cookie
+ * expiration date detection.
+ * - Fix a valgrind warning.
+ *
+ * Revision 1.35 2007/01/01 19:36:37 fabiankeil
+ * Integrate a modified version of Wil Mahan's
+ * zlib patch (PR #895531).
+ *
+ * Revision 1.34 2006/12/29 19:08:22 fabiankeil
+ * Reverted parts of my last commit
+ * to keep error handling working.
+ *
+ * Revision 1.33 2006/12/29 18:04:40 fabiankeil
+ * Fixed gcc43 conversion warnings.
+ *
+ * Revision 1.32 2006/12/06 19:14:23 fabiankeil
+ * Added prototype for get_destination_from_headers().
+ *
+ * Revision 1.31 2006/08/17 17:15:10 fabiankeil
+ * - Back to timegm() using GnuPG's replacement if necessary.
+ * Using mktime() and localtime() could add a on hour offset if
+ * the randomize factor was big enough to lead to a summer/wintertime
+ * switch.
+ *
+ * - Removed now-useless Privoxy 3.0.3 compatibility glue.
+ *
+ * - Moved randomization code into pick_from_range().
+ *
+ * - Changed parse_header_time definition.
+ * time_t isn't guaranteed to be signed and
+ * if it isn't, -1 isn't available as error code.
+ * Changed some variable types in client_if_modified_since()
+ * because of the same reason.
+ *
+ * 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
