Hi, I am trying to understand the headers being received by a squid server response. The output of a netcat connect to 10.0.0.2:1234 is below. I assume proxy.office is 10.0.0.2, but where does the "deny" come from, and where does proxy2.external fit in? Any help would be appreciated. quintin@quintin-VAIO:/tmp$ nc -v 10.0.0.2 1234 Connection to 10.0.0.2 1234 port [tcp/*] succeeded!
