- * Revisions :
- * $Log: cgi.h,v $
- * Revision 1.23 2002/03/24 16:18:15 jongfoster
- * Removing old logo
- *
- * Revision 1.22 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.21 2002/03/07 03:48:38 oes
- * - Changed built-in images from GIF to PNG
- * (with regard to Unisys patent issue)
- * - Added a 4x4 pattern PNG which is less intrusive
- * than the logo but also clearly marks the deleted banners
- *
- * Revision 1.20 2002/03/04 17:53:22 oes
- * Fixed compiled warning
- *
- * Revision 1.19 2002/01/21 00:33:52 jongfoster
- * Adding map_block_keep() to save a few bytes in the edit-actions-list HTML.
- *
- * Revision 1.18 2001/11/16 00:46:31 jongfoster
- * Fixing compiler warnings
- *
- * Revision 1.17 2001/10/23 21:48:19 jongfoster
- * Cleaning up error handling in CGI functions - they now send back
- * a HTML error page and should never cause a FATAL error. (Fixes one
- * potential source of "denial of service" attacks).
- *
- * CGI actions file editor that works and is actually useful.
- *
- * Ability to toggle JunkBuster remotely using a CGI call.
- *
- * You can turn off both the above features in the main configuration
- * file, e.g. if you are running a multi-user proxy.
- *
- * Revision 1.16 2001/09/16 17:08:54 jongfoster
- * Moving simple CGI functions from cgi.c to new file cgisimple.c
- *
- * Revision 1.15 2001/09/16 15:02:35 jongfoster
- * Adding i.j.b/robots.txt.
- * Inlining add_stats() since it's only ever called from one place.
- *
- * Revision 1.14 2001/09/16 11:38:02 jongfoster
- * Splitting fill_template() into 2 functions:
- * template_load() loads the file
- * template_fill() performs the PCRS regexps.
- * This is because the CGI edit interface has a "table row"
- * template which is used many times in the page - this
- * change means it's only loaded from disk once.
- *
- * Revision 1.13 2001/09/16 11:00:10 jongfoster
- * New function alloc_http_response, for symmetry with free_http_response
- *
- * Revision 1.12 2001/09/13 23:31:25 jongfoster
- * Moving image data to cgi.c rather than cgi.h.
- *
- * Revision 1.11 2001/08/05 16:06:20 jongfoster
- * Modifiying "struct map" so that there are now separate header and
- * "map_entry" structures. This means that functions which modify a
- * map no longer need to return a pointer to the modified map.
- * Also, it no longer reverses the order of the entries (which may be
- * important with some advanced template substitutions).
- *
- * Revision 1.10 2001/08/01 21:19:22 jongfoster
- * Moving file version information to a separate CGI page.
- *
- * Revision 1.9 2001/08/01 00:17:54 jongfoster
- * Adding prototype for map_conditional
- *
- * Revision 1.8 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 1.7 2001/07/29 18:43:08 jongfoster
- * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
- * ANSI C rules.
- *
- * Revision 1.6 2001/06/29 21:45:41 oes
- * Indentation, CRLF->LF, Tab-> Space
- *
- * Revision 1.5 2001/06/29 13:22:44 oes
- * - Cleaned up
- * - Added new functions: default_exports(), make_menu(),
- * error_response() etc, ranamed others and changed
- * param and return types.
- * - Removed HTTP/HTML snipplets
- * - Removed logentry from cancelled commit
- *
- * Revision 1.4 2001/06/09 10:50:58 jongfoster
- * Changing "show URL info" handler to new style.
