 * 
 * Revision 1.5  2001/06/01 10:31:51  oes
 * Added character class matching to trivimatch; renamed to simplematch
 * 
 * Revision 1.4  2001/05/31 17:32:31  oes
 * 
 *  - Enhanced domain part globbing with infix and prefix asterisk
 *    matching and optional unanchored operation
 * 
 * Revision 1.3  2001/05/29 23:10:09  oes
 * 
 * 
 *  - Introduced chomp()
 *  - Moved strsav() from showargs to miscutil
 * 
 * Revision 1.2  2001/05/29 09:50:24  jongfoster
 * Unified blocklist/imagelist/permissionslist.
 * File format is still under discussion, but the internal changes
 * are (mostly) done.
 * 
 * Also modified interceptor behaviour:
 * - We now intercept all URLs beginning with one of the following
 *   prefixes (and *only* these prefixes):
 *     * http://i.j.b/
 *     * http://ijbswa.sf.net/config/
 *     * http://ijbswa.sourceforge.net/config/
 * - New interceptors "home page" - go to http://i.j.b/ to see it.
 * - Internal changes so that intercepted and fast redirect pages
 *   are not replaced with an image.
 * - Interceptors now have the option to send a binary page direct
 *   to the client. (i.e. ijb-send-banner uses this)
 * - Implemented show-url-info interceptor.  (Which is why I needed
 *   the above interceptors changes - a typical URL is
 *   "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
 *   The previous mechanism would not have intercepted that, and
 *   if it had been intercepted then it then it would have replaced
 *   it with an image.)
 * 
 * Revision 1.1.1.1  2001/05/15 13:59:00  oes
 * Initial import of version 2.9.3 source tree
 *
