64 * Remove FEATURE_COOKIE_JAR.
66 * Revision 1.78 2008/08/02 08:23:22 fabiankeil
67 * If the enforce-blocks directive is used with FEATURE_FORCE_LOAD
68 * disabled, log a message that blocks will always be enforced

70 * Reported by Pietro Leone.
72 * Revision 1.77 2008/05/26 16:13:22 fabiankeil

111 * #1763173 from Stefan Huehner: declare unload_configfile() static.
113 * Revision 1.65 2007/07/21 11:51:36 fabiankeil
114 * As Hal noticed, checking dispatch_cgi() as the last cruncher
115 * looks like a bug if CGI requests are blocked unintentionally,
116 * so don't do it unless the user enabled the new config option
117 * "allow-cgi-request-crunching".

124 * - Remove an unnecessary temporary memory allocation.
125 * - Don't log anything to the console when running as
126 * daemon and no errors occurred.
128 * Revision 1.63 2007/04/09 18:11:36 fabiankeil
129 * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
131 * Revision 1.62 2007/03/17 15:20:05 fabiankeil
132 * New config option: enforce-blocks.
134 * Revision 1.61 2007/03/16 16:47:35 fabiankeil
135 * - Mention other reasons why acl directive loading might have failed.
136 * - Don't log the acl source if the acl destination is to blame.
138 * Revision 1.60 2007/01/27 13:09:16 fabiankeil
139 * Add new config option "templdir" to
140 * change the templates directory.
142 * Revision 1.59 2006/12/31 17:56:38 fabiankeil
143 * Added config option accept-intercepted-requests
144 * and disabled it by default.
146 * Revision 1.58 2006/12/31 14:24:29 fabiankeil
147 * Fix gcc43 compiler warnings.

165 * Same limitations as for the action files apply.
168 * Revision 1.53 2006/09/06 18:45:03 fabiankeil
169 * Incorporate modified version of Roland Rosenfeld's patch to
170 * optionally access the user-manual via Privoxy. Closes patch 679075.
172 * Formatting changed to Privoxy style, added call to
173 * cgi_error_no_template if the requested file doesn't
174 * exist and modified check whether or not Privoxy itself
175 * should serve the manual. Should work cross-platform now.
177 * Revision 1.52 2006/09/06 10:43:32 fabiankeil
178 * Added config option enable-remote-http-toggle
179 * to specify if Privoxy should recognize special
180 * headers (currently only X-Filter) to change its

193 * Don't forget to malloc space for the null terminator...
195 * Revision 1.48.2.6 2006/01/29 23:10:56 david__schmidt

198 * Revision 1.48.2.5 2003/05/08 15:17:25 oes
199 * Closed two memory leaks; hopefully the last remaining ones
200 * (in the main execution paths, anyway).
202 * Revision 1.48.2.4 2003/04/11 12:06:14 oes
203 * Addressed bug #719435

219 * Revision 1.47 2002/05/12 21:36:29 jongfoster
220 * Correcting function comments
222 * Revision 1.46 2002/04/26 12:55:14 oes

248 * Revision 1.38 2002/03/24 13:05:48 jongfoster
249 * Renaming re_filterfile to filterfile
251 * Revision 1.37 2002/03/16 23:54:06 jongfoster
252 * Adding graceful termination feature, to help look for memory leaks.
253 * If you enable this (which, by design, has to be done by hand
254 * editing config.h) and then go to http://i.j.b/die, then the program
255 * will exit cleanly after the *next* request. It should free all the
256 * memory that was used.
258 * Revision 1.36 2002/03/13 00:27:05 jongfoster
261 * Revision 1.35 2002/03/07 03:52:44 oes

277 * Replacing strsav() with string_append()
279 * Revision 1.29 2002/01/17 21:02:30 jongfoster
280 * Moving all our URL and URL pattern parsing code to urlmatch.c.
282 * Renaming free_url to free_url_spec, since it frees a struct url_spec.
284 * Revision 1.28 2001/12/30 14:07:32 steudten
285 * - Add signal handling (unix)
286 * - Add SIGHUP handler (unix)
287 * - Add creation of pidfile (unix)

289 * - Add entry 'SIGNALS' to manpage
290 * - Add exit message to logfile (unix)
292 * Revision 1.27 2001/11/07 00:02:13 steudten

299 * (change cwd to /, detach from controlling tty, set
300 * process group and session leader to the own process.
302 * Add some fatal-error log message for failed malloc().
303 * Add '-d' if compiled with 'configure --with-debug' to
304 * enable debug output.
306 * Revision 1.25 2001/10/25 03:40:48 david__schmidt
307 * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
308 * threads to call select() simultaneously. So, it's time to do a real, live,
309 * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
310 * (native). Both versions will work, but using __OS2__ offers multi-threading.
312 * Revision 1.24 2001/10/23 21:40:30 jongfoster
313 * Added support for enable-edit-actions and enable-remote-toggle config
316 * Revision 1.23 2001/10/07 15:36:00 oes

326 * Revision 1.20 2001/07/30 22:08:36 jongfoster
327 * Tidying up #defines:
328 * - All feature #defines are now of the form FEATURE_xxx
329 * - Permanently turned off WIN_GUI_EDIT
330 * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
332 * Revision 1.19 2001/07/15 17:45:16 jongfoster
333 * Removing some unused #includes
335 * Revision 1.18 2001/07/13 14:01:14 oes
336 * - Removed all #ifdef PCRS
337 * - Removed vim-settings
339 * Revision 1.17 2001/06/29 13:31:03 oes
340 * - Improved comments
341 * - Fixed (actionsfile) and sorted hashes
342 * - Introduced admin_address and proxy-info-url
343 * as config parameters
344 * - Renamed config->proxy_args_invocation (which didn't have
345 * the invocation but the options!) to config->proxy_args
346 * - Various adaptions
347 * - Removed logentry from cancelled commit
349 * Revision 1.16 2001/06/09 10:55:28 jongfoster

352 * Revision 1.15 2001/06/07 23:13:40 jongfoster
353 * Merging ACL and forward files into config file.
354 * Cosmetic: Sorting config file options alphabetically.
355 * Cosmetic: Adding brief syntax comments to config file options.
357 * Revision 1.14 2001/06/07 14:46:25 joergs
358 * Missing make_path() added for re_filterfile.
360 * Revision 1.13 2001/06/05 22:33:54 jongfoster
362 * Fixed minor memory leak.
363 * Also now uses make_path to prepend the pathnames.
365 * Revision 1.12 2001/06/05 20:04:09 jongfoster
366 * Now uses _snprintf() in place of snprintf() under Win32.
368 * Revision 1.11 2001/06/04 18:31:58 swa
369 * files are now prefixed with either `confdir' or `logdir'.
370 * `make redhat-dist' replaces both entries confdir and logdir
373 * Revision 1.10 2001/06/03 19:11:54 oes
374 * introduced confdir option
376 * Revision 1.9 2001/06/01 20:06:24 jongfoster
377 * Removed support for "tinygif" option - moved to actions file.
379 * Revision 1.8 2001/05/31 21:27:13 jongfoster
380 * Removed many options from the config file and into the
381 * "actions" file: add_forwarded, suppress_vanilla_wafer,
382 * wafer, add_header, user_agent, referer, from
383 * Also globally replaced "permission" with "action".
385 * Revision 1.7 2001/05/29 09:50:24 jongfoster
386 * Unified blocklist/imagelist/permissionslist.
387 * File format is still under discussion, but the internal changes
390 * Also modified interceptor behaviour:
391 * - We now intercept all URLs beginning with one of the following
392 * prefixes (and *only* these prefixes):
394 * * http://ijbswa.sf.net/config/
395 * * http://ijbswa.sourceforge.net/config/
396 * - New interceptors "home page" - go to http://i.j.b/ to see it.
397 * - Internal changes so that intercepted and fast redirect pages
398 * are not replaced with an image.
399 * - Interceptors now have the option to send a binary page direct
400 * to the client. (i.e. ijb-send-banner uses this)
401 * - Implemented show-url-info interceptor. (Which is why I needed
402 * the above interceptors changes - a typical URL is
403 * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
404 * The previous mechanism would not have intercepted that, and
405 * if it had been intercepted then it then it would have replaced
408 * Revision 1.6 2001/05/26 00:28:36 jongfoster
409 * Automatic reloading of config file.
410 * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
411 * Most of the global variables have been moved to a new
412 * struct configuration_spec, accessed through csp->config->globalname
413 * Most of the globals remaining are used by the Win32 GUI.
415 * Revision 1.5 2001/05/25 22:34:30 jongfoster
418 * Revision 1.4 2001/05/22 18:46:04 oes
420 * - Enabled filtering banners by size rather than URL
421 * by adding patterns that replace all standard banner
422 * sizes with the "Junkbuster" gif to the re_filterfile
424 * - Enabled filtering WebBugs by providing a pattern
425 * which kills all 1x1 images
427 * - Added support for PCRE_UNGREEDY behaviour to pcrs,
428 * which is selected by the (nonstandard and therefore
429 * capital) letter 'U' in the option string.
430 * It causes the quantifiers to be ungreedy by default.
431 * Appending a ? turns back to greedy (!).
433 * - Added a new interceptor ijb-send-banner, which
434 * sends back the "Junkbuster" gif. Without imagelist or
435 * MSIE detection support, or if tinygif = 1, or the
436 * URL isn't recognized as an imageurl, a lame HTML
437 * explanation is sent instead.
439 * - Added new feature, which permits blocking remote
440 * script redirects and firing back a local redirect
442 * The feature is conditionally compiled, i.e. it
443 * can be disabled with --disable-fast-redirects,
444 * plus it must be activated by a "fast-redirects"
445 * line in the config file, has its own log level
446 * and of course wants to be displayed by show-proxy-args
447 * Note: Boy, all the #ifdefs in 1001 locations and
448 * all the fumbling with configure.in and acconfig.h
449 * were *way* more work than the feature itself :-(
451 * - Because a generic redirect template was needed for
452 * this, tinygif = 3 now uses the same.
454 * - Moved GIFs, and other static HTTP response templates
459 * - Removed some >400 CRs again (Jon, you really worked
462 * Revision 1.3 2001/05/20 01:21:20 jongfoster
463 * Version 2.9.4 checkin.
464 * - Merged popupfile and cookiefile, and added control over PCRS
465 * filtering, in new "permissionsfile".
466 * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
467 * file error you now get a message box (in the Win32 GUI) rather
468 * than the program exiting with no explanation.
469 * - Made killpopup use the PCRS MIME-type checking and HTTP-header
471 * - Removed tabs from "config"
472 * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
473 * - Bumped up version number.
475 * Revision 1.2 2001/05/17 23:01:01 oes
476 * - Cleaned CRLF's from the sources and related files
478 * Revision 1.1.1.1 2001/05/15 13:58:58 oes
479 * Initial import of version 2.9.3 source tree
