+ * name change related issues
+ *
+ * Revision 1.19 2002/03/16 23:54:06 jongfoster
+ * Adding graceful termination feature, to help look for memory leaks.
+ * If you enable this (which, by design, has to be done by hand
+ * editing config.h) and then go to http://i.j.b/die, then the program
+ * will exit cleanly after the *next* request. It should free all the
+ * memory that was used.
+ *
+ * Revision 1.18 2002/03/12 01:44:49 oes
+ * Changed default for "blocked" image from jb logo to checkboard pattern
+ *
+ * Revision 1.17 2002/03/08 16:43:18 oes
+ * Added choice beween GIF and PNG built-in images
+ *
+ * Revision 1.16 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 1.15 2002/03/06 22:54:35 jongfoster
+ * Automated function-comment nitpicking.
+ *
+ * Revision 1.14 2002/03/02 04:14:50 david__schmidt
+ * Clean up a little CRLF unpleasantness that suddenly appeared
+ *
+ * Revision 1.13 2002/02/21 00:10:37 jongfoster
+ * Adding send-banner?type=auto option
+ *
+ * Revision 1.12 2002/01/23 01:03:32 jongfoster
+ * Fixing gcc [CygWin] compiler warnings
+ *
+ * Revision 1.11 2002/01/23 00:01:04 jongfoster
+ * Adding cgi_transparent_gif() for http://i.j.b/t
+ * Adding missing html_encode() to many CGI functions.
+ * Adding urlmatch.[ch] to http://i.j.b/show-version
+ *
+ * Revision 1.10 2002/01/17 21:10:37 jongfoster
+ * Changes to cgi_show_url_info to use new matching code from urlmatch.c.
+ * Also fixing a problem in the same function with improperly quoted URLs
+ * in output HTML, and adding code to handle https:// URLs correctly.
+ *
+ * Revision 1.9 2001/11/30 23:09:15 jongfoster
+ * Now reports on FEATURE_CGI_EDIT_ACTIONS
+ * Removing FEATURE_DENY_GZIP from template
+ *
+ * Revision 1.8 2001/11/13 00:14:07 jongfoster
+ * Fixing stupid bug now I've figured out what || means.
+ * (It always returns 0 or 1, not one of it's paramaters.)
+ *
+ * Revision 1.7 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 1.6 2001/10/14 22:00:32 jongfoster
+ * Adding support for a 404 error when an invalid CGI page is requested.
+ *
+ * Revision 1.5 2001/10/07 15:30:41 oes
+ * Removed FEATURE_DENY_GZIP
