You have explicitly configured Squid instructing it that traffic
arriving on port 3129 has been intercepted.

You then sent Squid a port-80 syntax message with TCP packet destination
IP:port of

It is for this reason that all our interception tutorials state in bold
that its a very good idea to firewall the 3129 port such that no
software, even localhost may send traffic directly into it.
