- * Revision 1.84 2009/01/14 16:14:36 fabiankeil

- *
- * Revision 1.83 2008/12/20 14:53:55 fabiankeil

- *
- * Revision 1.80 2008/08/31 15:59:03 fabiankeil
- * There's no reason to let remote toggling support depend

- *
- * Revision 1.78 2008/08/02 08:23:22 fabiankeil

- * disabled, log a message that blocks will always be enforced

- *
- * Revision 1.65 2007/07/21 11:51:36 fabiankeil
- * As Hal noticed, checking dispatch_cgi() as the last cruncher
- * looks like a bug if CGI requests are blocked unintentionally,
- * so don't do it unless the user enabled the new config option
- * "allow-cgi-request-crunching".
- *
- * Revision 1.64 2007/05/21 10:44:08 fabiankeil

- * - Don't log anything to the console when running as
- * daemon and no errors occurred.
- *
- * Revision 1.63 2007/04/09 18:11:36 fabiankeil
- * Don't mistake VC++'s _snprintf() for a snprintf() replacement.
- *
- * Revision 1.62 2007/03/17 15:20:05 fabiankeil

- * to work around the browser bug reported
- * in BR #1570678.
- *
- * Revision 1.56 2006/12/17 17:04:51 fabiankeil
- * Move the <br> in the generated HTML for the config
- * options from the beginning of the string to its end.
- * Keeps the white space in balance.

- *
- * Revision 1.53 2006/09/06 18:45:03 fabiankeil
- * Incorporate modified version of Roland Rosenfeld's patch to
- * optionally access the user-manual via Privoxy. Closes patch 679075.
- *
- * Formatting changed to Privoxy style, added call to
- * cgi_error_no_template if the requested file doesn't
- * exist and modified check whether or not Privoxy itself
- * should serve the manual. Should work cross-platform now.
- *
- * Revision 1.52 2006/09/06 10:43:32 fabiankeil
- * Added config option enable-remote-http-toggle
- * to specify if Privoxy should recognize special

- * behaviour. Disabled by default.
- *
- * Revision 1.51 2006/09/06 09:23:37 fabiankeil

- * Revision 1.48.2.4 2003/04/11 12:06:14 oes
- * Addressed bug #719435

- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the

- *
- * Revision 1.36 2002/03/13 00:27:05 jongfoster

- * Add DBG() Macro.
- * Add some fatal-error log message for failed malloc().
- * Add '-d' if compiled with 'configure --with-debug' to
- * enable debug output.
- *
- * Revision 1.25 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
- *
- * Revision 1.24 2001/10/23 21:40:30 jongfoster

- *
- * Revision 1.20 2001/07/30 22:08:36 jongfoster

- * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS
- *
- * Revision 1.19 2001/07/15 17:45:16 jongfoster
- * Removing some unused #includes

- * Revision 1.18 2001/07/13 14:01:14 oes
- * - Removed all #ifdef PCRS
- * - Removed vim-settings
- *
- * Revision 1.17 2001/06/29 13:31:03 oes
- * - Improved comments
- * - Fixed (actionsfile) and sorted hashes
- * - Introduced admin_address and proxy-info-url

- *
- * Revision 1.13 2001/06/05 22:33:54 jongfoster
- *
- * Fixed minor memory leak.
- * Also now uses make_path to prepend the pathnames.
- *
- * Revision 1.12 2001/06/05 20:04:09 jongfoster
- * Now uses _snprintf() in place of snprintf() under Win32.
- *
- * Revision 1.11 2001/06/04 18:31:58 swa
- * files are now prefixed with either `confdir' or `logdir'.
- * `make redhat-dist' replaces both entries confdir and logdir
- * with redhat values
- *
- * Revision 1.10 2001/06/03 19:11:54 oes
- * introduced confdir option
- *
- * Revision 1.9 2001/06/01 20:06:24 jongfoster
- * Removed support for "tinygif" option - moved to actions file.
- *
- * Revision 1.8 2001/05/31 21:27:13 jongfoster
- * Removed many options from the config file and into the
- * "actions" file: add_forwarded, suppress_vanilla_wafer,
- * wafer, add_header, user_agent, referer, from
- * Also globally replaced "permission" with "action".
- *
- * Revision 1.7 2001/05/29 09:50:24 jongfoster
- * Unified blocklist/imagelist/permissionslist.
- * File format is still under discussion, but the internal changes
- * are (mostly) done.
- *
- * Also modified interceptor behaviour:
- * - We now intercept all URLs beginning with one of the following
- * prefixes (and *only* these prefixes):
- * * http://i.j.b/
- * * http://ijbswa.sf.net/config/
- * * http://ijbswa.sourceforge.net/config/
- * - New interceptors "home page" - go to http://i.j.b/ to see it.
- * - Internal changes so that intercepted and fast redirect pages
- * are not replaced with an image.
- * - Interceptors now have the option to send a binary page direct
- * to the client. (i.e. ijb-send-banner uses this)
- * - Implemented show-url-info interceptor. (Which is why I needed
- * the above interceptors changes - a typical URL is
- * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif".
- * The previous mechanism would not have intercepted that, and
- * if it had been intercepted then it then it would have replaced
- * it with an image.)
- *
- * Revision 1.6 2001/05/26 00:28:36 jongfoster
- * Automatic reloading of config file.
- * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32).
- * Most of the global variables have been moved to a new
- * struct configuration_spec, accessed through csp->config->globalname
- * Most of the globals remaining are used by the Win32 GUI.
- *
- * Revision 1.5 2001/05/25 22:34:30 jongfoster
- * Hard tabs->Spaces
- *
- * Revision 1.4 2001/05/22 18:46:04 oes
- *
- * - Enabled filtering banners by size rather than URL
- * by adding patterns that replace all standard banner
- * sizes with the "Junkbuster" gif to the re_filterfile
- *
- * - Enabled filtering WebBugs by providing a pattern
- * which kills all 1x1 images
- *
- * - Added support for PCRE_UNGREEDY behaviour to pcrs,
- * which is selected by the (nonstandard and therefore
- * capital) letter 'U' in the option string.
- * It causes the quantifiers to be ungreedy by default.
- * Appending a ? turns back to greedy (!).
- *
- * - Added a new interceptor ijb-send-banner, which
- * sends back the "Junkbuster" gif. Without imagelist or
- * MSIE detection support, or if tinygif = 1, or the
- * URL isn't recognized as an imageurl, a lame HTML
- * explanation is sent instead.
- *
- * - Added new feature, which permits blocking remote
- * script redirects and firing back a local redirect
- * to the browser.
- * The feature is conditionally compiled, i.e. it
- * can be disabled with --disable-fast-redirects,
- * plus it must be activated by a "fast-redirects"
- * line in the config file, has its own log level
- * and of course wants to be displayed by show-proxy-args
- * Note: Boy, all the #ifdefs in 1001 locations and
- * all the fumbling with configure.in and acconfig.h
- * were *way* more work than the feature itself :-(
- *
- * - Because a generic redirect template was needed for
- * this, tinygif = 3 now uses the same.
- *
- * - Moved GIFs, and other static HTTP response templates
- * to project.h
- *
- * - Some minor fixes
- *
- * - Removed some >400 CRs again (Jon, you really worked
- * a lot! ;-)
- *
- * Revision 1.3 2001/05/20 01:21:20 jongfoster
- * Version 2.9.4 checkin.
- * - Merged popupfile and cookiefile, and added control over PCRS
- * filtering, in new "permissionsfile".
- * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration
- * file error you now get a message box (in the Win32 GUI) rather
- * than the program exiting with no explanation.
- * - Made killpopup use the PCRS MIME-type checking and HTTP-header
- * skipping.
- * - Removed tabs from "config"
- * - Moved duplicated url parsing code in "loaders.c" to a new funcition.
- * - Bumped up version number.
- *
- * Revision 1.2 2001/05/17 23:01:01 oes
- * - Cleaned CRLF's from the sources and related files
- *
- * Revision 1.1.1.1 2001/05/15 13:58:58 oes
- * Initial import of version 2.9.3 source tree
- *
- *
