39 * Revision 1.40 2001/10/26 17:40:47 oes
40 * Moved ijb_isspace and ijb_tolower to project.h
41 * Removed http->user_agent, csp->referrer and csp->accept_types
43 * Revision 1.39 2001/10/25 03:45:02 david__schmidt
44 * Adding a (void*) cast to freez() because Visual Age C++ won't expand the
45 * macro when called with a cast; so moving the cast to the macro def'n
46 * seems to both eliminate compiler warnings (on darwin and OS/2, anyway) and
47 * doesn't make macro expansion complain. Hope this works for everyone else
50 * Revision 1.38 2001/10/23 21:19:04 jongfoster
51 * New error-handling support: jb_err type and JB_ERR_xxx constants
52 * CGI functions now return a jb_err, and their parameters map is const.
53 * Support for RUNTIME_FEATUREs to enable/disable config editor
54 * Adding a few comments
56 * Revision 1.37 2001/10/14 22:14:01 jongfoster
57 * Removing name_length field from struct cgi_dispatcher, as this is
58 * now calculated at runtime from the "name" field.
60 * Revision 1.36 2001/10/10 16:45:15 oes
61 * Added LIMIT_CONNECT action and string
62 * Fixed HTTP message line termination
63 * Added CFORBIDDEN HTTP message
65 * Revision 1.35 2001/10/07 18:06:43 oes
66 * Added status member to struct http_request
68 * Revision 1.34 2001/10/07 15:45:25 oes
69 * Added url member to struct http_request and commented all
74 * Added ACTION_DOWNGRADE and ACTION_NO_COMPRESSION
76 * Replaced struct client_state members rejected,
77 * force, active and toggled_on with "flags" bitmap.
79 * Added CSP_FLAG_MODIFIED and CSP_FLAG_CHUNKED
81 * Added buffer_limit to struct configuration_spec
83 * Revision 1.33 2001/09/20 13:30:08 steudten
85 * Make freez() more secure in case of: if (exp) { free(z) ; a=*z }
86 * Last case will set z to NULL in free(z) and thats bad..
88 * Revision 1.32 2001/09/16 23:02:51 jongfoster
91 * Revision 1.31 2001/09/16 13:20:29 jongfoster
92 * Rewrite of list library. Now has seperate header and list_entry
93 * structures. Also added a large sprinking of assert()s to the list
96 * Revision 1.30 2001/09/13 23:52:00 jongfoster

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

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

136 * - Added ACTION_DEANIMATE
137 * - Removed all #ifdef PCRS
139 * Revision 1.20 2001/06/29 21:45:41 oes
140 * Indentation, CRLF->LF, Tab-> Space
142 * Revision 1.19 2001/06/29 13:33:36 oes

146 * - Introduced config.my_ip_addr_str, config.my_hostname,
147 * config.admin_address and config.proxy_info_url

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

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