*nod*
I was very aware and would expect that the there were two distinctly different TCP connections, even though the 2nd one is caused by the 1st one. What I was not aware of is if Squid would send traffic to web servers from a known port and thus would be able to filter based on that. I can't say as I'm surprised or disappointed by that fact.
