- * Revisions :
- * $Log: cgisimple.c,v $
- * 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
- *
- * Revision 1.4 2001/10/02 15:31:12 oes
- * Introduced show-request cgi
- *
- * Revision 1.3 2001/09/22 16:34:44 jongfoster
- * Removing unneeded #includes
- *
- * Revision 1.2 2001/09/19 18:01:11 oes
- * Fixed comments; cosmetics
- *
