Re: [squid-users] Single squid in a squid -> filter -> squid

He's right, it will work but the loopback trigger will happen and be =
logged,=20
What I found easier was using a simple proxy for the outer proxy so that
you don't have the caching overhead, and using squid internally using=20
ACL's.. The bigger problem is that you can't tell squid to use a certain
parent for 1 outgoing ACL and a different one for another (as far as I=20
can tell). So I have basically accomplished this (still waiting on a few =
bugs
in squid-3 that are showstoppers before I can move it to production) by
writing a patch to DansGuardian that would add an X-Naughty header
when a page is naughty, and squid uses an external ACL to check on=20
the reply header (this needed a patch) and then used deny_info on the
http_reply_access acl (which also needed a patch). Once I have this all
stable I'll send the patches upstream.. if you want them now you can=20
email me offlist or whatever, at least one of them is in squids bugzilla
but needs to be rewritten cleaner for inclusion.. Hope this helps..

network->squid instance X->dansguardian->squid instance X
^
loop detection will trigger here.

Please, see the FAQ on running two instances, and then setup it up.
