+ If you use any <literal><ulink
+ url="../user-manual/actions-file.html#FILTER">filter</ulink></literal> action,
+ such as filtering banners by size, web-bugs etc, or the <literal><ulink
+ url="../user-manual/actions-file.html#DEANIMATE-GIFS">deanimate-gifs</ulink></literal>
+ action, the entire document must be loaded into memory in order for the filtering
+ mechanism to work, and nothing is sent to the browser during this time.
+</para>
+<para>
+ The loading time typically does not really change much in real numbers, but
+ the feeling is different, because most browsers are able to start rendering
+ incomplete content, giving the user a feeling of "it works". This effect is
+ more noticeable on slower dialup connections. Extremely large documents
+ may have some impact on the time to load the page where there is filtering
+ being done. But overall, the difference should be very minimal. If there is a
+ big impact, then probably some other situation is contributing (like
+ anti-virus software).
+ </para>
+<para>
+ Filtering is automatically disabled for inappropriate MIME types. But note
+ that if the web server mis-reports the MIME type, then content that should
+ not be filtered, could be. <application>Privoxy</application> only knows how
+ to differentiate filterable content because of the MIME type as reported by
+ the server, or because of some configuration setting that enables/disables
+ filtering.

+<para>
+ <ulink url="http://config.privoxy.org/">http://config.privoxy.org/</ulink> is the
+ address of <application>Privoxy</application>'s built-in user interface, and
+ <ulink url="http://p.p/">http://p.p/</ulink> is a shortcut for it.
+</para>
+<para>
+ Since <application>Privoxy</application> sits between your web browser and the Internet,
+ it can simply intercept requests for these addresses and answer them with its built-in
+ <quote>web server</quote>.
+</para>
+<para>
+ This also makes for a good test for your browser configuration: If entering the
+ URL <ulink url="http://config.privoxy.org/">http://config.privoxy.org/</ulink>
+ takes you to a page saying <quote>This is Privoxy ...</quote>, everything is OK.
+ If you get a page saying <quote>Privoxy is not working</quote> instead, then
+ your browser didn't use <application>Privoxy</application> for the request,
+ hence it could not be intercepted, and you have accessed the <emphasis>real</emphasis>
+ web site at config.privoxy.org.
+</para>
+<para>
+ Note that config.privoxy.org resolves to a public IP address.
+ If you use config.privoxy.org as ping or traceroute target you will
+ reach the system on the Internet (Privoxy can't intercept ICMP requests).
+ If you want to ping the system Privoxy runs on,
+ you should use its IP address or local DNS name (if it has got one).

+ If you run both the browser and &my-app; locally, you cannot hide your IP

+ There are many publicly usable "anonymous" proxies out there, which
+ provide a further level of indirection between you and the web server.
+</para>
+<para>
+ However, these proxies are called "anonymous" because you don't need
+ to authenticate, not because they would offer any real anonymity.
+ Most of them will log your IP address and make it available to the
+ authorities in case you violate the law of the country they run in. In fact
+ you can't even rule out that some of them only exist to *collect* information
+ on (those suspicious) people with a more than average preference for privacy.
