* Revisions :
* $Log: cgi.h,v $
+ * Revision 1.34 2008/04/17 14:40:48 fabiankeil
+ * Provide get_http_time() with the buffer size so it doesn't
+ * have to blindly assume that the buffer is big enough.
+ *
+ * Revision 1.33 2007/01/28 13:41:17 fabiankeil
+ * - Add HEAD support to finish_http_response.
+ * - Add error favicon to internal HTML error messages.
+ *
+ * Revision 1.32 2006/12/17 17:53:39 fabiankeil
+ * Suppress the toggle link if remote toggling is disabled.
+ *
+ * Revision 1.31 2006/07/18 14:48:45 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 1.29.2.2 2004/02/17 13:30:23 oes
+ * Moved cgi_error_disabled() from cgiedit.c to
+ * cgi.c to re-enable build with --disable-editor.
+ * Fixes Bug #892744. Thanks to Matthew Fischer
+ * for spotting.
+ *
+ * Revision 1.29.2.1 2003/12/17 16:33:28 oes
+ * Added prototype of new function cgi_redirect
+ *
+ * Revision 1.29 2002/05/19 11:33:21 jongfoster
+ * If a CGI error was not handled, and propogated back to
+ * dispatch_known_cgi(), then it was assumed to be "out of memory".
+ * This gave a very misleading error message.
+ *
+ * Now other errors will cause a simple message giving the error
+ * number and asking the user to report a bug.
+ *
+ * Bug report:
+ * http://sourceforge.net/tracker/index.php?func=detail
+ * &aid=557905&group_id=11118&atid=111118
+ *
+ * Revision 1.28 2002/04/26 12:54:03 oes
+ * New function add_help_link
+ *
+ * Revision 1.27 2002/04/24 02:16:51 oes
+ * Moved get_char_param, get_string_param and get_number_param here from cgiedit.c
+ *
+ * Revision 1.26 2002/04/10 13:38:35 oes
+ * load_template signature changed
+ *
+ * Revision 1.25 2002/04/08 20:50:25 swa

+ * 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

+ * 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
*
