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

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

119 * - Permanently turned off WIN_GUI_EDIT
120 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
122 * Revision 1.15 2001/07/29 17:41:10 jongfoster

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