* $Log: cgi.h,v $
+ * Revision 1.24 2002/03/26 22:29:54 swa
+ * we have a new homepage!
+ *
+ * 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
