RE: [squid-users] One slow Website Through Proxy
Thanks Amos, guess I learned something simple that I should have already known when troubleshooting these things always capture packets on both sides of squid. I was only looking at the data between the client PC and squid. Had I looked at the packets on the other side of squid I more than likely would have caught this one.
