<P>
<A HREF="http://www.squidguard.org/">squidGuard</A> is
a free (GPL), flexible and efficient filter and
redirector program for squid. It lets you define multiple access
rules with different restrictions for different user groups on a squid
cache. squidGuard uses squid standard redirector interface.</P>
<H3>Central Squid Server</H3>
<P>The Smart Neighbour [URL disappeared]
(or 'Central Squid Server' - CSS) is a cut-down
version of Squid without HTTP or object caching functionality. The
CSS deals only with ICP messages. Instead of caching objects, the CSS
records the availability of objects in each of its neighbour caches.
Caches that have smart neighbours update each smart neighbour with the
status of their cache by sending ICP_STORE_NOTIFY/ICP_RELEASE_NOTIFY
messages upon storing/releasing an object from their cache. The CSS
maintains an up to date 'object map' recording the availability of
objects in its neighbouring caches.</P>

provided by

requires a license (priced by the number of seats) but evaluation licenses are available.</P>
