00062 * - All feature #defines are now of the form FEATURE_xxx
00063 * - Permanently turned off WIN_GUI_EDIT
00064 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
00065 *
00066 * Revision 1.8 2001/07/29 18:43:08 jongfoster
00067 * Changing #ifdef _FILENAME_H to FILENAME_H_INCLUDED, to conform to
00068 * ANSI C rules.
00069 *
00070 * Revision 1.7 2001/07/19 19:02:53 haroon
00071 * Added define for LOG_LEVEL_POPUPS
00072 *
00073 * Revision 1.6 2001/07/13 13:59:22 oes
00074 * - Added LOG_LEVEL_DEANIMATE
00075 * - Changed LOG_LEVEL_CLF
00076 * - Removed all #ifdef PCRS
00077 *
00078 * Revision 1.5 2001/05/26 17:25:14 jongfoster
00079 * Added support for CLF (Common Log Format) and fixed LOG_LEVEL_LOG
00080 *
00081 * Revision 1.4 2001/05/25 21:56:06 jongfoster
00082 * Added FIXME comment to (broken) LOG_LEVEL_LOG
00083 *
00084 * Revision 1.3 2001/05/22 18:46:04 oes
00085 *
00086 * - Enabled filtering banners by size rather than URL
00087 * by adding patterns that replace all standard banner
00088 * sizes with the "Junkbuster" gif to the re_filterfile
00089 *
00090 * - Enabled filtering WebBugs by providing a pattern
00091 * which kills all 1x1 images
00092 *
00093 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
00094 * which is selected by the (nonstandard and therefore
00095 * capital) letter 'U' in the option string.
00096 * It causes the quantifiers to be ungreedy by default.
00097 * Appending a ? turns back to greedy (!).
00098 *
00099 * - Added a new interceptor ijb-send-banner, which
00100 * sends back the "Junkbuster" gif. Without imagelist or
00101 * MSIE detection support, or if tinygif = 1, or the
00102 * URL isn't recognized as an imageurl, a lame HTML
00103 * explanation is sent instead.
00104 *
00105 * - Added new feature, which permits blocking remote
00106 * script redirects and firing back a local redirect
00107 * to the browser.
00108 * The feature is conditionally compiled, i.e. it
00109 * can be disabled with --disable-fast-redirects,
00110 * plus it must be activated by a "fast-redirects"
00111 * line in the config file, has its own log level
00112 * and of course wants to be displayed by show-proxy-args
00113 * Note: Boy, all the #ifdefs in 1001 locations and
00114 * all the fumbling with configure.in and acconfig.h
00115 * were *way* more work than the feature itself :-(
00116 *
00117 * - Because a generic redirect template was needed for
00118 * this, tinygif = 3 now uses the same.
00119 *
00120 * - Moved GIFs, and other static HTTP response templates
00121 * to project.h
00122 *
00123 * - Some minor fixes
00124 *
00125 * - Removed some >400 CRs again (Jon, you really worked
00126 * a lot! ;-)
00127 *
00128 * Revision 1.2 2001/05/20 01:11:40 jongfoster
00129 * Added support for LOG_LEVEL_FATAL
00130 * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
00131 * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
00132 *
00133 * Revision 1.1.1.1 2001/05/15 13:58:51 oes
00134 * Initial import of version 2.9.3 source tree
00135 *
