  - Do you have a VirtualHostMonster instance in the root of your site?

  - Is squid expecting to run as a "reverse" proxy here?  The presence of
    the 'http://...' in the Z2.log suggests that Squid believes Zope to
    be a parent cache, rather than an origin server.

  - Can you test SquidGuard at the command line?  It should expect to
    read a line containing the requsted URL and some other data (I don't
    recall the syntax, but the Squid docs for redirectors would call it
    out) and return a single line for each line read.  E.g.::

    $ /path/to/squidguard
    http://www.example.com/index.html <other args here>
 
http://localhost:9080/VirtualHostBase/http/localhost:80/dms/VirtualHostRoot/index.html
