39 * Revision 1.43 2001/11/22 21:57:51 jongfoster
40 * Making action_spec->flags into an unsigned long rather than just an
42 * Adding ACTION_NO_COOKIE_KEEP
44 * Revision 1.42 2001/11/05 21:42:41 steudten
45 * Include DBG() macro.
47 * Revision 1.41 2001/10/28 19:12:06 jongfoster
48 * Adding ijb_toupper()
50 * Revision 1.40 2001/10/26 17:40:47 oes
51 * Moved ijb_isspace and ijb_tolower to project.h
52 * Removed http->user_agent, csp->referrer and csp->accept_types
54 * Revision 1.39 2001/10/25 03:45:02 david__schmidt
55 * Adding a (void*) cast to freez() because Visual Age C++ won't expand the
56 * macro when called with a cast; so moving the cast to the macro def'n
57 * seems to both eliminate compiler warnings (on darwin and OS/2, anyway) and
58 * doesn't make macro expansion complain. Hope this works for everyone else
61 * Revision 1.38 2001/10/23 21:19:04 jongfoster
62 * New error-handling support: jb_err type and JB_ERR_xxx constants
63 * CGI functions now return a jb_err, and their parameters map is const.
64 * Support for RUNTIME_FEATUREs to enable/disable config editor
65 * Adding a few comments
67 * Revision 1.37 2001/10/14 22:14:01 jongfoster
68 * Removing name_length field from struct cgi_dispatcher, as this is
69 * now calculated at runtime from the "name" field.
71 * Revision 1.36 2001/10/10 16:45:15 oes
72 * Added LIMIT_CONNECT action and string
73 * Fixed HTTP message line termination
74 * Added CFORBIDDEN HTTP message
76 * Revision 1.35 2001/10/07 18:06:43 oes
77 * Added status member to struct http_request
79 * Revision 1.34 2001/10/07 15:45:25 oes

92 * Added buffer_limit to struct configuration_spec
94 * Revision 1.33 2001/09/20 13:30:08 steudten
96 * Make freez() more secure in case of: if (exp) { free(z) ; a=*z }
97 * Last case will set z to NULL in free(z) and thats bad..
99 * Revision 1.32 2001/09/16 23:02:51 jongfoster
102 * Revision 1.31 2001/09/16 13:20:29 jongfoster
103 * Rewrite of list library. Now has seperate header and list_entry
104 * structures. Also added a large sprinking of assert()s to the list

116 * Revision 1.27 2001/08/05 16:06:20 jongfoster
117 * Modifiying "struct map" so that there are now separate header and
118 * "map_entry" structures. This means that functions which modify a
119 * map no longer need to return a pointer to the modified map.
120 * Also, it no longer reverses the order of the entries (which may be
121 * important with some advanced template substitutions).
123 * Revision 1.26 2001/07/30 22:08:36 jongfoster

140 * Revision 1.22 2001/07/15 17:51:41 jongfoster
141 * Renaming #define STATIC to STATIC_PCRE
143 * Revision 1.21 2001/07/13 14:03:19 oes

147 * - Added ACTION_DEANIMATE
148 * - Removed all #ifdef PCRS
150 * Revision 1.20 2001/06/29 21:45:41 oes
151 * Indentation, CRLF->LF, Tab-> Space

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