 *
 *    Revision 1.7  2001/07/19 19:02:53  haroon
 *    Added define for LOG_LEVEL_POPUPS
 *
 *    Revision 1.6  2001/07/13 13:59:22  oes
 *     - Added LOG_LEVEL_DEANIMATE
 *     - Changed LOG_LEVEL_CLF
 *     - Removed all #ifdef PCRS

 *
 *    Revision 1.3  2001/05/22 18:46:04  oes
 *
 *    - Enabled filtering banners by size rather than URL
 *      by adding patterns that replace all standard banner
 *      sizes with the "Junkbuster" gif to the re_filterfile
 *
 *    - Enabled filtering WebBugs by providing a pattern
 *      which kills all 1x1 images
 *
 *    - Added support for PCRE_UNGREEDY behaviour to pcrs,
 *      which is selected by the (nonstandard and therefore
 *      capital) letter 'U' in the option string.
 *      It causes the quantifiers to be ungreedy by default.
 *      Appending a ? turns back to greedy (!).
 *
 *    - Added a new interceptor ijb-send-banner, which
 *      sends back the "Junkbuster" gif. Without imagelist or
 *      MSIE detection support, or if tinygif = 1, or the
 *      URL isn't recognized as an imageurl, a lame HTML
 *      explanation is sent instead.
 *
 *    - Added new feature, which permits blocking remote
 *      script redirects and firing back a local redirect
 *      to the browser.
 *      The feature is conditionally compiled, i.e. it
 *      can be disabled with --disable-fast-redirects,
 *      plus it must be activated by a "fast-redirects"
 *      line in the config file, has its own log level
 *      and of course wants to be displayed by show-proxy-args
 *      Note: Boy, all the #ifdefs in 1001 locations and
 *      all the fumbling with configure.in and acconfig.h
 *      were *way* more work than the feature itself :-(
 *
 *    - Because a generic redirect template was needed for
 *      this, tinygif = 3 now uses the same.
 *
 *    - Moved GIFs, and other static HTTP response templates
 *      to project.h
 *
 *    - Some minor fixes
 *
 *    - Removed some >400 CRs again (Jon, you really worked
 *      a lot! ;-)
 *
 *    Revision 1.2  2001/05/20 01:11:40  jongfoster
 *    Added support for LOG_LEVEL_FATAL
 *    Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
 *    and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
 *
 *    Revision 1.1.1.1  2001/05/15 13:58:51  oes
 *    Initial import of version 2.9.3 source tree
