45 * Revision 1.32 2002/03/07 03:46:17 oes
46 * Fixed compiler warnings
48 * Revision 1.31 2002/03/06 23:02:57 jongfoster
51 * Revision 1.30 2002/03/05 22:43:45 david__schmidt
52 * - Better error reporting on OS/2
53 * - Fix double-slash comment (oops)
55 * Revision 1.29 2002/03/04 23:45:13 jongfoster
56 * Printing thread ID if using Win32 native threads
58 * Revision 1.28 2002/03/04 17:59:59 oes
59 * Deleted deletePidFile(), cosmetics
61 * Revision 1.27 2002/03/04 02:08:01 david__schmidt
62 * Enable web editing of actions file on OS/2 (it had been broken all this time!)
64 * Revision 1.26 2002/01/09 19:05:45 steudten
65 * Fix big memory leak.
67 * Revision 1.25 2002/01/09 14:32:08 oes
68 * Added support for gmtime_r and localtime_r.
70 * Revision 1.24 2001/12/30 14:07:32 steudten
71 * - Add signal handling (unix)
72 * - Add SIGHUP handler (unix)
73 * - Add creation of pidfile (unix)
74 * - Add action 'top' in rc file (RH)
75 * - Add entry 'SIGNALS' to manpage
76 * - Add exit message to logfile (unix)
78 * Revision 1.23 2001/11/07 00:02:13 steudten
79 * Add line number in error output for lineparsing for
80 * actionsfile and configfile.
81 * Special handling for CLF added.
83 * Revision 1.22 2001/11/05 23:43:05 steudten
84 * Add time+date to log files.
86 * Revision 1.21 2001/10/25 03:40:47 david__schmidt
87 * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
88 * threads to call select() simultaneously. So, it's time to do a real, live,
89 * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
90 * (native). Both versions will work, but using __OS2__ offers multi-threading.
92 * Revision 1.20 2001/09/16 23:04:34 jongfoster
95 * Revision 1.19 2001/09/13 20:08:06 jongfoster

106 * - All feature #defines are now of the form FEATURE_xxx
107 * - Permanently turned off WIN_GUI_EDIT
108 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
110 * Revision 1.15 2001/07/29 17:41:10 jongfoster
111 * Now prints thread ID for each message (pthreads only)
113 * Revision 1.14 2001/07/19 19:03:48 haroon
114 * - Added case for LOG_LEVEL_POPUPS
116 * Revision 1.13 2001/07/13 13:58:58 oes
117 * - Added case for LOG_LEVEL_DEANIMATE
118 * - Removed all #ifdef PCRS
120 * Revision 1.12 2001/06/09 10:55:28 jongfoster

123 * Revision 1.11 2001/06/01 18:14:49 jongfoster
124 * Changing the calls to strerr() to check HAVE_STRERR (which is defined
125 * in config.h if appropriate) rather than the NO_STRERR macro.
127 * Revision 1.10 2001/05/29 11:52:21 oes
128 * Conditional compilation of w32_socket_error

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