* Revisions :
* $Log: filters.c,v $
+ * Revision 1.33 2001/09/16 17:05:14 jongfoster
+ * Removing unused #include showarg.h
+ *
+ * Revision 1.32 2001/09/16 13:21:27 jongfoster
+ * Changes to use new list functions.
+ *
+ * Revision 1.31 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 1.30 2001/09/16 11:00:10 jongfoster
+ * New function alloc_http_response, for symmetry with free_http_response
+ *
+ * Revision 1.29 2001/09/13 23:32:40 jongfoster
+ * Moving image data to cgi.c rather than cgi.h
+ * Fixing a GPF under Win32 (and any other OS that protects global
+ * constants from being written to).
+ *
+ * Revision 1.28 2001/09/10 10:18:51 oes
+ * Silenced compiler warnings
+ *
+ * Revision 1.27 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 1.26 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 1.25 2001/07/26 10:09:46 oes
* Made browser detection a little less naive
