43 * Adding a few comments
45 * Revision 1.37 2001/10/14 22:14:01 jongfoster
46 * Removing name_length field from struct cgi_dispatcher, as this is
47 * now calculated at runtime from the "name" field.

50 * Added LIMIT_CONNECT action and string
51 * Fixed HTTP message line termination
52 * Added CFORBIDDEN HTTP message
54 * Revision 1.35 2001/10/07 18:06:43 oes
55 * Added status member to struct http_request
57 * Revision 1.34 2001/10/07 15:45:25 oes
58 * Added url member to struct http_request and commented all

74 * Make freez() more secure in case of: if (exp) { free(z) ; a=*z }
75 * Last case will set z to NULL in free(z) and thats bad..
77 * Revision 1.32 2001/09/16 23:02:51 jongfoster
80 * Revision 1.31 2001/09/16 13:20:29 jongfoster
81 * Rewrite of list library. Now has seperate header and list_entry
82 * structures. Also added a large sprinking of assert()s to the list
85 * Revision 1.30 2001/09/13 23:52:00 jongfoster

95 * Modifiying "struct map" so that there are now separate header and
96 * "map_entry" structures. This means that functions which modify a
97 * map no longer need to return a pointer to the modified map.
98 * Also, it no longer reverses the order of the entries (which may be
99 * important with some advanced template substitutions).

126 * - Removed all #ifdef PCRS
128 * Revision 1.20 2001/06/29 21:45:41 oes
129 * Indentation, CRLF->LF, Tab-> Space
131 * Revision 1.19 2001/06/29 13:33:36 oes

142 * Revision 1.18 2001/06/09 10:57:39 jongfoster
143 * Adding definition of BUFFER_SIZE.
144 * Changing struct cgi_dispatcher to use "const" strings.
146 * Revision 1.17 2001/06/07 23:15:09 jongfoster
147 * Merging ACL and forward files into config file.
148 * Moving struct gateway members into struct forward_spec
149 * Removing config->proxy_args_gateways
150 * Cosmetic: Adding a few comments
152 * Revision 1.16 2001/06/04 18:31:58 swa
153 * files are now prefixed with either `confdir' or `logdir'.
154 * `make redhat-dist' replaces both entries confdir and logdir
157 * Revision 1.15 2001/06/04 11:28:53 swa

163 * changed struct interceptors to struct cgi_dispatcher,
164 * moved HTML stuff to cgi.h
166 * Revision 1.13 2001/06/01 20:05:36 jongfoster
167 * Support for +image-blocker{}: added ACTION_IMAGE_BLOCKER
168 * constant, and removed csp->tinygif.
170 * Revision 1.12 2001/06/01 18:49:17 jongfoster
171 * Replaced "list_share" with "list" - the tiny memory gain was not
172 * worth the extra complexity.
174 * Revision 1.11 2001/06/01 10:32:47 oes
175 * Added constants for anchoring selection bitmap
177 * Revision 1.10 2001/05/31 21:33:53 jongfoster
178 * Changes for new actions file, replacing permissionsfile
179 * and parts of the config file. Also added support for
182 * Revision 1.9 2001/05/31 17:32:31 oes
184 * - Enhanced domain part globbing with infix and prefix asterisk
185 * matching and optional unanchored operation
187 * Revision 1.8 2001/05/29 20:09:15 joergs
188 * HTTP_REDIRECT_TEMPLATE fixed.
190 * Revision 1.7 2001/05/29 09:50:24 jongfoster
191 * Unified blocklist/imagelist/actionslist.
192 * File format is still under discussion, but the internal changes
195 * Also modified interceptor behaviour:
196 * - We now intercept all URLs beginning with one of the following
197 * prefixes (and *only* these prefixes):
199 * * http://ijbswa.sf.net/config/
200 * * http://ijbswa.sourceforge.net/config/
201 * - New interceptors "home page" - go to http://i.j.b/ to see it.
202 * - Internal changes so that intercepted and fast redirect pages
203 * are not replaced with an image.
204 * - Interceptors now have the option to send a binary page direct
205 * to the client. (i.e. ijb-send-banner uses this)
206 * - Implemented show-url-info interceptor. (Which is why I needed
207 * the above interceptors changes - a typical URL is
208 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
209 * The previous mechanism would not have intercepted that, and
210 * if it had been intercepted then it then it would have replaced
213 * Revision 1.6 2001/05/27 22:17:04 oes
215 * - re_process_buffer no longer writes the modified buffer
216 * to the client, which was very ugly. It now returns the
217 * buffer, which it is then written by chat.
219 * - content_length now adjusts the Content-Length: header
220 * for modified documents rather than crunch()ing it.
221 * (Length info in csp->content_length, which is 0 for
222 * unmodified documents)
224 * - For this to work, sed() is called twice when filtering.
226 * Revision 1.5 2001/05/26 00:28:36 jongfoster
227 * Automatic reloading of config file.
228 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
229 * Most of the global variables have been moved to a new
230 * struct configuration_spec, accessed through csp->config->globalname
231 * Most of the globals remaining are used by the Win32 GUI.
233 * Revision 1.4 2001/05/22 18:46:04 oes
235 * - Enabled filtering banners by size rather than URL
236 * by adding patterns that replace all standard banner
237 * sizes with the "Junkbuster" gif to the re_filterfile
239 * - Enabled filtering WebBugs by providing a pattern
240 * which kills all 1x1 images
242 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
243 * which is selected by the (nonstandard and therefore
244 * capital) letter 'U' in the option string.
245 * It causes the quantifiers to be ungreedy by default.
246 * Appending a ? turns back to greedy (!).
248 * - Added a new interceptor ijb-send-banner, which
249 * sends back the "Junkbuster" gif. Without imagelist or
250 * MSIE detection support, or if tinygif = 1, or the
251 * URL isn't recognized as an imageurl, a lame HTML
252 * explanation is sent instead.
254 * - Added new feature, which permits blocking remote
255 * script redirects and firing back a local redirect
257 * The feature is conditionally compiled, i.e. it
258 * can be disabled with --disable-fast-redirects,
259 * plus it must be activated by a "fast-redirects"
260 * line in the config file, has its own log level
261 * and of course wants to be displayed by show-proxy-args
262 * Note: Boy, all the #ifdefs in 1001 locations and
263 * all the fumbling with configure.in and acconfig.h
264 * were *way* more work than the feature itself :-(
266 * - Because a generic redirect template was needed for
267 * this, tinygif = 3 now uses the same.
269 * - Moved GIFs, and other static HTTP response templates
274 * - Removed some >400 CRs again (Jon, you really worked
277 * Revision 1.3 2001/05/20 01:21:20 jongfoster
278 * Version 2.9.4 checkin.
279 * - Merged popupfile and cookiefile, and added control over PCRS
280 * filtering, in new "actionsfile".
281 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
282 * file error you now get a message box (in the Win32 GUI) rather
283 * than the program exiting with no explanation.
284 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
286 * - Removed tabs from "config"
287 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
288 * - Bumped up version number.
290 * Revision 1.2 2001/05/17 23:01:01 oes
291 * - Cleaned CRLF's from the sources and related files
293 * Revision 1.1.1.1 2001/05/15 13:59:03 oes
294 * Initial import of version 2.9.3 source tree
