39 * Revision 1.41 2001/10/28 19:12:06 jongfoster
40 * Adding ijb_toupper()
42 * Revision 1.40 2001/10/26 17:40:47 oes
43 * Moved ijb_isspace and ijb_tolower to project.h
44 * Removed http->user_agent, csp->referrer and csp->accept_types
46 * Revision 1.39 2001/10/25 03:45:02 david__schmidt
47 * Adding a (void*) cast to freez() because Visual Age C++ won't expand the
48 * macro when called with a cast; so moving the cast to the macro def'n
49 * seems to both eliminate compiler warnings (on darwin and OS/2, anyway) and
50 * doesn't make macro expansion complain. Hope this works for everyone else
53 * Revision 1.38 2001/10/23 21:19:04 jongfoster
54 * New error-handling support: jb_err type and JB_ERR_xxx constants
55 * CGI functions now return a jb_err, and their parameters map is const.
56 * Support for RUNTIME_FEATUREs to enable/disable config editor
57 * Adding a few comments
59 * Revision 1.37 2001/10/14 22:14:01 jongfoster
60 * Removing name_length field from struct cgi_dispatcher, as this is
61 * now calculated at runtime from the "name" field.

64 * Added LIMIT_CONNECT action and string
65 * Fixed HTTP message line termination
66 * Added CFORBIDDEN HTTP message
68 * Revision 1.35 2001/10/07 18:06:43 oes
69 * Added status member to struct http_request
71 * Revision 1.34 2001/10/07 15:45:25 oes

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

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

139 * - Added ACTION_DEANIMATE
140 * - Removed all #ifdef PCRS
142 * Revision 1.20 2001/06/29 21:45:41 oes
143 * Indentation, CRLF->LF, Tab-> Space

156 * Revision 1.18 2001/06/09 10:57:39 jongfoster
157 * Adding definition of BUFFER_SIZE.
158 * Changing struct cgi_dispatcher to use "const" strings.
160 * Revision 1.17 2001/06/07 23:15:09 jongfoster
161 * Merging ACL and forward files into config file.
162 * Moving struct gateway members into struct forward_spec
163 * Removing config->proxy_args_gateways
164 * Cosmetic: Adding a few comments
166 * Revision 1.16 2001/06/04 18:31:58 swa
167 * files are now prefixed with either `confdir' or `logdir'.
168 * `make redhat-dist' replaces both entries confdir and logdir
171 * Revision 1.15 2001/06/04 11:28:53 swa
172 * redirect did not work due to missing /

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