RE: [squid-users] Bad Requests

Ok, here is my squid.conf.mlist. I think this issue only happens when squid
forwards the requests to DansGuardian. When I put the concerned domains in
the "always_direct" directive they work fine. Here is my set up:

Client ----> Squid ----> DG ----> Mcafee Webshield ----> Internet

99.9% of the sites work just fine, except a few. DG is a new implementation
I am working on to replace all the blocking ACLs I have in squid. Do you
see anything in this config that could cause this?

If your squid is working normal to other sites, then it may be blocked by
Admin's there.
Post your consolidated squid.conf file ( grep -v "^#" squid.conf >
squid.conf.mlist" )
