39 * Revision 1.37 2001/10/14 22:14:01 jongfoster
40 * Removing name_length field from struct cgi_dispatcher, as this is
41 * now calculated at runtime from the "name" field.

44 * Added LIMIT_CONNECT action and string
45 * Fixed HTTP message line termination
46 * Added CFORBIDDEN HTTP message
48 * Revision 1.35 2001/10/07 18:06:43 oes
49 * Added status member to struct http_request
51 * Revision 1.34 2001/10/07 15:45:25 oes
52 * Added url member to struct http_request and commented all
57 * Added ACTION_DOWNGRADE and ACTION_NO_COMPRESSION
59 * Replaced struct client_state members rejected,
60 * force, active and toggled_on with "flags" bitmap.
62 * Added CSP_FLAG_MODIFIED and CSP_FLAG_CHUNKED
64 * Added buffer_limit to struct configuration_spec
66 * Revision 1.33 2001/09/20 13:30:08 steudten
68 * Make freez() more secure in case of: if (exp) { free(z) ; a=*z }
69 * Last case will set z to NULL in free(z) and thats bad..
71 * Revision 1.32 2001/09/16 23:02:51 jongfoster
74 * Revision 1.31 2001/09/16 13:20:29 jongfoster
75 * Rewrite of list library. Now has seperate header and list_entry
76 * structures. Also added a large sprinking of assert()s to the list
79 * Revision 1.30 2001/09/13 23:52:00 jongfoster
80 * Support for both static and dynamically generated CGI pages

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

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