- *
- * Revision 1.24 2001/12/30 14:07:32 steudten
- * - Add signal handling (unix)
- * - Add SIGHUP handler (unix)

- * (native). Both versions will work, but using __OS2__ offers multi-threading.

- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.15 2001/07/29 17:41:10 jongfoster
- * Now prints thread ID for each message (pthreads only)
- *
- * Revision 1.14 2001/07/19 19:03:48 haroon
- * - Added case for LOG_LEVEL_POPUPS
- *
- * Revision 1.13 2001/07/13 13:58:58 oes

- *
- * Revision 1.6 2001/05/25 21:55:08 jongfoster
- * Now cleans up properly on FATAL (removes taskbar icon etc)
- *
- * Revision 1.5 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 1.4 2001/05/21 19:32:54 jongfoster
- * Added another #ifdef _WIN_CONSOLE
- *
- * Revision 1.3 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 1.2 2001/05/17 22:42:01 oes
- * - Cleaned CRLF's from the sources and related files
- * - Repaired logging for REF and FRC
- *
- * Revision 1.1.1.1 2001/05/15 13:58:51 oes
- * Initial import of version 2.9.3 source tree
- *
