62 * Fixed compiler warnings
64 * Revision 1.31 2002/03/06 23:02:57 jongfoster
67 * Revision 1.30 2002/03/05 22:43:45 david__schmidt
68 * - Better error reporting on OS/2
69 * - Fix double-slash comment (oops)
71 * Revision 1.29 2002/03/04 23:45:13 jongfoster
72 * Printing thread ID if using Win32 native threads
74 * Revision 1.28 2002/03/04 17:59:59 oes
75 * Deleted deletePidFile(), cosmetics
77 * Revision 1.27 2002/03/04 02:08:01 david__schmidt
78 * Enable web editing of actions file on OS/2 (it had been broken all this time!)
80 * Revision 1.26 2002/01/09 19:05:45 steudten
81 * Fix big memory leak.
83 * Revision 1.25 2002/01/09 14:32:08 oes
84 * Added support for gmtime_r and localtime_r.
86 * Revision 1.24 2001/12/30 14:07:32 steudten
87 * - Add signal handling (unix)
88 * - Add SIGHUP handler (unix)
89 * - Add creation of pidfile (unix)
90 * - Add action 'top' in rc file (RH)
91 * - Add entry 'SIGNALS' to manpage
92 * - Add exit message to logfile (unix)
94 * Revision 1.23 2001/11/07 00:02:13 steudten
95 * Add line number in error output for lineparsing for
96 * actionsfile and configfile.
97 * Special handling for CLF added.

100 * Add time+date to log files.
102 * Revision 1.21 2001/10/25 03:40:47 david__schmidt
103 * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
104 * threads to call select() simultaneously. So, it's time to do a real, live,
105 * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
106 * (native). Both versions will work, but using __OS2__ offers multi-threading.

123 * - Permanently turned off WIN_GUI_EDIT
124 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
126 * Revision 1.15 2001/07/29 17:41:10 jongfoster

152 * Revision 1.7 2001/05/26 15:21:28 jongfoster
153 * Activity animation in Win32 GUI now works even if debug==0
155 * Revision 1.6 2001/05/25 21:55:08 jongfoster
156 * Now cleans up properly on FATAL (removes taskbar icon etc)
158 * Revision 1.5 2001/05/22 18:46:04 oes
160 * - Enabled filtering banners by size rather than URL
161 * by adding patterns that replace all standard banner
162 * sizes with the "Junkbuster" gif to the re_filterfile
164 * - Enabled filtering WebBugs by providing a pattern
165 * which kills all 1x1 images
167 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
168 * which is selected by the (nonstandard and therefore
169 * capital) letter 'U' in the option string.
170 * It causes the quantifiers to be ungreedy by default.
171 * Appending a ? turns back to greedy (!).
173 * - Added a new interceptor ijb-send-banner, which
174 * sends back the "Junkbuster" gif. Without imagelist or
175 * MSIE detection support, or if tinygif = 1, or the
176 * URL isn't recognized as an imageurl, a lame HTML
177 * explanation is sent instead.
179 * - Added new feature, which permits blocking remote
180 * script redirects and firing back a local redirect
182 * The feature is conditionally compiled, i.e. it
183 * can be disabled with --disable-fast-redirects,
184 * plus it must be activated by a "fast-redirects"
185 * line in the config file, has its own log level
186 * and of course wants to be displayed by show-proxy-args
187 * Note: Boy, all the #ifdefs in 1001 locations and
188 * all the fumbling with configure.in and acconfig.h
189 * were *way* more work than the feature itself :-(
191 * - Because a generic redirect template was needed for
192 * this, tinygif = 3 now uses the same.
194 * - Moved GIFs, and other static HTTP response templates
199 * - Removed some >400 CRs again (Jon, you really worked
202 * Revision 1.4 2001/05/21 19:32:54 jongfoster
203 * Added another #ifdef _WIN_CONSOLE
205 * Revision 1.3 2001/05/20 01:11:40 jongfoster
206 * Added support for LOG_LEVEL_FATAL
207 * Renamed LOG_LEVEL_FRC to LOG_LEVEL_FORCE,
208 * and LOG_LEVEL_REF to LOG_LEVEL_RE_FILTER
210 * Revision 1.2 2001/05/17 22:42:01 oes
211 * - Cleaned CRLF's from the sources and related files
212 * - Repaired logging for REF and FRC
214 * Revision 1.1.1.1 2001/05/15 13:58:51 oes
215 * Initial import of version 2.9.3 source tree
