41 * Fixed HTTP message line termination
42 * Added CFORBIDDEN HTTP message
44 * Revision 1.35 2001/10/07 18:06:43 oes
45 * Added status member to struct http_request
47 * Revision 1.34 2001/10/07 15:45:25 oes
48 * Added url member to struct http_request and commented all
53 * Added ACTION_DOWNGRADE and ACTION_NO_COMPRESSION

62 * Revision 1.33 2001/09/20 13:30:08 steudten
64 * Make freez() more secure in case of: if (exp) { free(z) ; a=*z }
65 * Last case will set z to NULL in free(z) and thats bad..
67 * Revision 1.32 2001/09/16 23:02:51 jongfoster
70 * Revision 1.31 2001/09/16 13:20:29 jongfoster
71 * Rewrite of list library. Now has seperate header and list_entry
72 * structures. Also added a large sprinking of assert()s to the list
75 * Revision 1.30 2001/09/13 23:52:00 jongfoster
76 * Support for both static and dynamically generated CGI pages

85 * Modifiying "struct map" so that there are now separate header and
86 * "map_entry" structures. This means that functions which modify a
87 * map no longer need to return a pointer to the modified map.
88 * Also, it no longer reverses the order of the entries (which may be
89 * important with some advanced template substitutions).
91 * Revision 1.26 2001/07/30 22:08:36 jongfoster

113 * comply to the scheme in configure.in
114 * - Added csp->content_type and its CT_* keys
115 * - Added ACTION_DEANIMATE
116 * - Removed all #ifdef PCRS
118 * Revision 1.20 2001/06/29 21:45:41 oes
119 * Indentation, CRLF->LF, Tab-> Space
121 * Revision 1.19 2001/06/29 13:33:36 oes
122 * - Improved comments
123 * - Introduced http_request.host_ip_addr_str
124 * - Introduced http_response.head_length
125 * - Introduced config.my_ip_addr_str, config.my_hostname,
126 * config.admin_address and config.proxy_info_url
127 * - Removed config.proxy_args_header and config.proxy_args_trailer,
128 * renamed config.proxy_args_invocation to config.proxy_args
129 * - Removed HTML snipplets and GIFs
130 * - Removed logentry from cancelled commit
132 * Revision 1.18 2001/06/09 10:57:39 jongfoster
133 * Adding definition of BUFFER_SIZE.
134 * Changing struct cgi_dispatcher to use "const" strings.
136 * Revision 1.17 2001/06/07 23:15:09 jongfoster
137 * Merging ACL and forward files into config file.
138 * Moving struct gateway members into struct forward_spec
139 * Removing config->proxy_args_gateways
140 * Cosmetic: Adding a few comments
142 * Revision 1.16 2001/06/04 18:31:58 swa
143 * files are now prefixed with either `confdir' or `logdir'.
144 * `make redhat-dist' replaces both entries confdir and logdir
147 * Revision 1.15 2001/06/04 11:28:53 swa
148 * redirect did not work due to missing /
150 * Revision 1.14 2001/06/03 11:03:48 oes
152 * added struct http_response,
153 * changed struct interceptors to struct cgi_dispatcher,
154 * moved HTML stuff to cgi.h
156 * Revision 1.13 2001/06/01 20:05:36 jongfoster
157 * Support for +image-blocker{}: added ACTION_IMAGE_BLOCKER
158 * constant, and removed csp->tinygif.
160 * Revision 1.12 2001/06/01 18:49:17 jongfoster
161 * Replaced "list_share" with "list" - the tiny memory gain was not
162 * worth the extra complexity.
164 * Revision 1.11 2001/06/01 10:32:47 oes
165 * Added constants for anchoring selection bitmap
167 * Revision 1.10 2001/05/31 21:33:53 jongfoster
168 * Changes for new actions file, replacing permissionsfile
169 * and parts of the config file. Also added support for
172 * Revision 1.9 2001/05/31 17:32:31 oes
174 * - Enhanced domain part globbing with infix and prefix asterisk
175 * matching and optional unanchored operation
177 * Revision 1.8 2001/05/29 20:09:15 joergs
178 * HTTP_REDIRECT_TEMPLATE fixed.
180 * Revision 1.7 2001/05/29 09:50:24 jongfoster
181 * Unified blocklist/imagelist/actionslist.
182 * File format is still under discussion, but the internal changes
185 * Also modified interceptor behaviour:
186 * - We now intercept all URLs beginning with one of the following
187 * prefixes (and *only* these prefixes):
189 * * http://ijbswa.sf.net/config/
190 * * http://ijbswa.sourceforge.net/config/
191 * - New interceptors "home page" - go to http://i.j.b/ to see it.
192 * - Internal changes so that intercepted and fast redirect pages
193 * are not replaced with an image.
194 * - Interceptors now have the option to send a binary page direct
195 * to the client. (i.e. ijb-send-banner uses this)
196 * - Implemented show-url-info interceptor. (Which is why I needed
197 * the above interceptors changes - a typical URL is
198 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
199 * The previous mechanism would not have intercepted that, and
200 * if it had been intercepted then it then it would have replaced
203 * Revision 1.6 2001/05/27 22:17:04 oes
205 * - re_process_buffer no longer writes the modified buffer
206 * to the client, which was very ugly. It now returns the
207 * buffer, which it is then written by chat.
209 * - content_length now adjusts the Content-Length: header
210 * for modified documents rather than crunch()ing it.
211 * (Length info in csp->content_length, which is 0 for
212 * unmodified documents)
214 * - For this to work, sed() is called twice when filtering.
216 * Revision 1.5 2001/05/26 00:28:36 jongfoster
217 * Automatic reloading of config file.
218 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
219 * Most of the global variables have been moved to a new
220 * struct configuration_spec, accessed through csp->config->globalname
221 * Most of the globals remaining are used by the Win32 GUI.
223 * Revision 1.4 2001/05/22 18:46:04 oes
225 * - Enabled filtering banners by size rather than URL
226 * by adding patterns that replace all standard banner
227 * sizes with the "Junkbuster" gif to the re_filterfile
229 * - Enabled filtering WebBugs by providing a pattern
230 * which kills all 1x1 images
232 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
233 * which is selected by the (nonstandard and therefore
234 * capital) letter 'U' in the option string.
235 * It causes the quantifiers to be ungreedy by default.
236 * Appending a ? turns back to greedy (!).
238 * - Added a new interceptor ijb-send-banner, which
239 * sends back the "Junkbuster" gif. Without imagelist or
240 * MSIE detection support, or if tinygif = 1, or the
241 * URL isn't recognized as an imageurl, a lame HTML
242 * explanation is sent instead.
244 * - Added new feature, which permits blocking remote
245 * script redirects and firing back a local redirect
247 * The feature is conditionally compiled, i.e. it
248 * can be disabled with --disable-fast-redirects,
249 * plus it must be activated by a "fast-redirects"
250 * line in the config file, has its own log level
251 * and of course wants to be displayed by show-proxy-args
252 * Note: Boy, all the #ifdefs in 1001 locations and
253 * all the fumbling with configure.in and acconfig.h
254 * were *way* more work than the feature itself :-(
256 * - Because a generic redirect template was needed for
257 * this, tinygif = 3 now uses the same.
259 * - Moved GIFs, and other static HTTP response templates
264 * - Removed some >400 CRs again (Jon, you really worked
267 * Revision 1.3 2001/05/20 01:21:20 jongfoster
268 * Version 2.9.4 checkin.
269 * - Merged popupfile and cookiefile, and added control over PCRS
270 * filtering, in new "actionsfile".
271 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
272 * file error you now get a message box (in the Win32 GUI) rather
273 * than the program exiting with no explanation.
274 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
276 * - Removed tabs from "config"
277 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
278 * - Bumped up version number.
280 * Revision 1.2 2001/05/17 23:01:01 oes
281 * - Cleaned CRLF's from the sources and related files
283 * Revision 1.1.1.1 2001/05/15 13:59:03 oes
284 * Initial import of version 2.9.3 source tree
