This feature allows routing of HTTP requests through a chain of
multiple proxies.
- It can be used to better protect privacy and confidentiality when
- accessing specific domains by routing requests to those domains
- through an anonymous public proxy (see e.g. <ulink
- url="http://www.multiproxy.org/anon_list.htm">http://www.multiproxy.org/anon_list.htm</ulink>)
- Or to use a caching proxy to speed up browsing. Or chaining to a parent
- proxy may be necessary because the machine that <application>Privoxy</application>
- runs on has no direct Internet access.
+</para>
+<para>
+ Forwarding can be used to chain Privoxy with a caching proxy to speed
+ up browsing. Using a parent proxy may also be necessary if the machine
+ that <application>Privoxy</application> runs on has no direct Internet access.
+</para>
+<para>
+ Note that parent proxies can severely decrease your privacy level.
+ For example a parent proxy could add your IP address to the request
+ headers and if it's a caching proxy it may add the <quote>Etag</quote>
+ header to revalidation requests again, even though you configured Privoxy
+ to remove it. It may also ignore Privoxy's header time randomization and use the
+ original values which could be used by the server as cookie replacement
+ to track your steps between visits.
