*
* Revision 1.92 2009/03/18 20:43:19 fabiankeil

*
* Revision 1.90 2009/03/07 17:58:02 fabiankeil

* case all bets are off anyway.
*
* Revision 1.89 2009/03/01 18:46:33 fabiankeil
* - Help clang understand that we aren't
* dereferencing NULL pointers here.
* - Some style fixes in the modified region.
*
* Revision 1.88 2009/02/28 10:57:10 fabiankeil

*
* Revision 1.86 2009/02/08 19:18:57 fabiankeil

* to the way it was before standard.action got removed and the
* changes from revision 1.84 have to be reverted.
*
* Revision 1.85 2009/01/22 12:06:26 fabiankeil

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

*
* Revision 1.82 2008/11/16 12:43:49 fabiankeil

*
* Revision 1.80 2008/08/31 15:59:03 fabiankeil

* Remove FEATURE_COOKIE_JAR.
*
* Revision 1.78 2008/08/02 08:23:22 fabiankeil
* If the enforce-blocks directive is used with FEATURE_FORCE_LOAD
* disabled, log a message that blocks will always be enforced
* instead of complaining about an unrecognized directive.

* Revision 1.66 2007/08/05 14:02:09 fabiankeil
* #1763173 from Stefan Huehner: declare unload_configfile() static.
*
* 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

* Fix gcc43 compiler warnings.
*

*
* 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
* headers (currently only X-Filter) to change its
* behaviour. Disabled by default.
*
* Revision 1.51 2006/09/06 09:23:37 fabiankeil

* 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

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

* process group and session leader to the own process.

*
* 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
* Added support for enable-edit-actions and enable-remote-toggle config
* file options.

* showargs.c.
*
* Revision 1.20 2001/07/30 22:08:36 jongfoster
* Tidying up #defines:
* - All feature #defines are now of the form FEATURE_xxx

* - 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
* as config parameters
* - Renamed config->proxy_args_invocation (which didn't have
* the invocation but the options!) to config->proxy_args
* - Various adaptions
* - Removed logentry from cancelled commit
*
* Revision 1.16 2001/06/09 10:55:28 jongfoster

*
* 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
