  * 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
