Re: [squid-users] WCCPv2 - only one service group redirecting

It looks like a problem with the config on the cisco side. you do not need a
reditrect in statment on the interface that is facing the Internet; the
responses are going to go to the Proxy as this is where they were sourced.
In other words you only need to intecept the traffic once the response will
go to the proxy on it's own.
