|
||
* As of r1.88, the show-status page can use a single line for

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

|
||
* Revision 1.86 2009/02/08 19:18:57 fabiankeil
|
||
* Now that we have the match-all.action file, the other action
|
||
* files changed their position in config->actions_file[] back
|
||
* to the way it was before standard.action got removed and the
|
||
* changes from revision 1.84 have to be reverted.

*

* 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,
|
||

* "allow-cgi-request-crunching".
|
||
*
|

* 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.

* - 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
|
||
* Changing BUFSIZ ==> BUFFER_SIZE
|
||
*
|
||
* Revision 1.15 2001/06/07 23:13:40 jongfoster
|
||
* Merging ACL and forward files into config file.
|
||
* Cosmetic: Sorting config file options alphabetically.
|
||
* Cosmetic: Adding brief syntax comments to config file options.
|
||
*
|
||
* Revision 1.14 2001/06/07 14:46:25 joergs
|
||
* Missing make_path() added for re_filterfile.
|
||
*
|
||
* 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
|

|
||
* Description : Called from `load_config'. It saves each non-empty
|
||
* and non-comment line from config into
|
||
* config->proxy_args. This is used to create the
|
||
* show-proxy-args page. On error, frees
|
||
* config->proxy_args and sets it to NULL
|
||
*
|
||
* Parameters :
|
||
* 1 : command = config setting that was found
|
||
* 2 : argument = the setting's argument (if any)
|
||
* 3 : config = Configuration to save into.
|
||
*
|
||
* Returns : N/A
