>   - Add a dok-tidy GNUMakefile target to clean up the messy HTML

>     2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.

>     toggle values are now a fatal error instead of being silently ignored.
>   - Terminate HTML lines in static error messages with \n instead of \r\n.
>   - Simplify cgi_error_unknown() a bit.

>     actually logging anything.
>   - Change ssplit()'s fourth parameter from int to size_t.
>     Fixes a clang complaint.
>   - Add a warning that the statistics currently can't be trusted.

>   - Change the expected status code returned for http://p.p/die depending
>     on whether or not FEATURE_GRACEFUL_TERMINATION is available.

>   - In get_content_type(), also recognize '.jpeg' as JPEG extension.
>   - Add '.png' to the list of recognized file extensions in

>   - Block ".gemius.pl/" which only seems to be used for user tracking.
>     Reported by johnd16 in #3002731. Additional input from Lee and movax.
>   - Disable banners-by-size filters for '.thinkgeek.com/'.
>     The filter only seems to catch pictures of the inventory.

>
> - Filter file improvements:
>   - Let the yahoo filter hide '.ads'.
>   - Let the msn filter hide overlay ads for Facebook 'likes' in search
>     results and elements with the id 's_notf_div'. They only seem to be
>     used to advertise site 'enhancements'.
>   - Let the js-events filter additionally disarm setInterval().
>     Suggested by dg1727 in #3423775.
>
> - Documentation improvements:
>   - Clarify the effect of compiling Privoxy with zlib support.
>     Suggested by dg1727 in #3423782.
>   - Point out that the SourceForge messaging system works like a black
>     hole and should thus not be used to contact individual developers.
>   - Mention some of the problems one can experience when not explicitly
>     configuring an IP addresses as listen address.
>   - Explicitly mention that hostnames can be used instead of IP addresses
>     for the listen-address, that only the first address returned will be
>     used and what happens if the address is invalid.
>     Requested by Calestyo in #3302213.

>     wait for a new client request.
>   - Remove a superfluous log message in forget_connection().
>   - In chat(), properly report missing server responses as such
>     instead of calling them empty.
>   - In forwarded_connect(), fix a log message nobody should ever see.
>   - Fix a log message in socks5_connect(), a failed write operation
>     was logged as failed read operation.
>   - Let load_one_actions_file() properly complain about a missing

> At present, Privoxy is known to run on Windows(95, 98, ME, 2000,
> XP, Vista), GNU/Linux (Ubuntu, RedHat, SuSE, Debian, Fedora, Gentoo and
> others), Mac OSX, OS/2, AmigaOS, FreeBSD, NetBSD, OpenBSD, Solaris, and
> various other flavors of Unix.
>
> In addition to the core features of ad blocking and cookie management,
> Privoxy provides many supplemental features, that give the end-user
> more control, more privacy and more freedom:
>
>
>     *  Supports "Connection: keep-alive". Outgoing connections can be kept
>        alive independently from the client. Currently not available on all
>        platforms.
>
>     *  Supports IPv6, provided the operating system does so too,
>        and the configure script detects it.
>
>     *  Supports tagging which allows to change the behaviour based on client
>        and server headers.
>
>     *  Can be run as an "intercepting" proxy, which obviates the need to
>        configure browsers individually.
>
>     *  Sophisticated actions and filters for manipulating both server and
>        client headers.
>
>     *  Can be chained with other proxies.
>
>     *  Integrated browser based configuration and control utility at
>        http://config.privoxy.org/ (shortcut: http://p.p/). Browser-based
>        tracing of rule and filter effects. Remote toggling.
>
>     *  Web page filtering (text replacements, removes banners based on size,
>        invisible <quote>web-bugs</quote> and HTML annoyances, etc.)
>
>     *  Modularized configuration that allows for standard settings and user
>        settings to reside in separate files, so that installing updated
> actions
>        files won't overwrite individual user settings.
>
>     *  Support for Perl Compatible Regular Expressions in the configuration
>        files, and a more sophisticated and flexible configuration syntax.
>
>     *  GIF de-animation.
>
>     *  Bypass many click-tracking scripts (avoids script redirection).
>
>     *  User-customizable HTML templates for most proxy-generated pages (e.g.
>        "blocked" page).
>
>     *  Auto-detection and re-reading of config file changes.
>
>     *  Most features are controllable on a per-site or per-location basis.

All the data continuously generated in your IT infrastructure 
contains a definitive record of customers, application performance, 
security threats, fraudulent activity, and more. Splunk takes this 
data and makes sense of it. IT sense. And common sense.
