* File : $Source: /cvsroot/ijbswa/current/cgi.c,v $
*
* Revisions :
* $Log: cgi.c,v $
+ * Revision 1.45 2002/03/06 22:54:35 jongfoster
+ * Automated function-comment nitpicking.
+ *
+ * Revision 1.44 2002/03/05 22:43:45 david__schmidt
+ * - Better error reporting on OS/2
+ * - Fix double-slash comment (oops)
+ *
+ * Revision 1.43 2002/03/05 21:33:45 david__schmidt
+ * - Re-enable OS/2 building after new parms were added
+ * - Fix false out of memory report when resolving CGI templates when no IP
+ * address is available of failed attempt (a la no such domain)
+ *
+ * Revision 1.42 2002/01/21 00:33:20 jongfoster
+ * Replacing strsav() with the safer string_append() or string_join().
+ * Adding map_block_keep() to save a few bytes in the edit-actions-list HTML.
+ * Adding missing html_encode() to error message generators.
+ * Adding edit-actions-section-swap and many "shortcuts" to the list of CGIs.
+ *
+ * Revision 1.41 2002/01/17 20:56:22 jongfoster
+ * Replacing hard references to the URL of the config interface
+ * with #defines from project.h
+ *
+ * Revision 1.40 2002/01/09 14:26:46 oes
+ * Added support for thread-safe gmtime_r call.
+ *
+ * Revision 1.39 2001/11/16 00:48:13 jongfoster
+ * Fixing a compiler warning
+ *
+ * Revision 1.38 2001/11/13 00:31:21 jongfoster
+ * - Adding new CGIs for use by non-JavaScript browsers:
+ * edit-actions-url-form
+ * edit-actions-add-url-form
+ * edit-actions-remove-url-form
+ * - Fixing make_menu()'s HTML generation - it now quotes the href parameter.
+ * - Fixing || bug.
+ *
+ * Revision 1.37 2001/11/01 14:28:47 david__schmidt
+ * Show enablement/disablement status in almost all templates.
+ * There is a little trickiness here: apparent recursive resolution of
+ * @if-enabled-then@ caused the toggle template to show status out-of-phase with
+ * the actual enablement status. So a similar construct,
+ * @if-enabled-display-then@, is used to resolve the status display on non-'toggle'
+ * templates.
+ *
+ * Revision 1.36 2001/10/26 17:33:27 oes
+ * marginal bugfix
+ *
* Revision 1.35 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
* Revision 1.34 2001/10/18 22:22:09 david__schmidt
* Only show "Local support" on templates conditionally:
* - if either 'admin-address' or 'proxy-info-url' are uncommented in config
- * - if not, no Local support section appears are removed automatically
+ * - if not, no Local support section appears
*
* Revision 1.33 2001/10/14 22:28:41 jongfoster
* Fixing stupid typo.
