Packet captures can tell you whether other Squid-ICAP server connections

In other words, basic network troubleshooting steps...
As I said, they live on the same host, so it can't be a network problem.
FYI, that conclusion does not follow. Even on the same host there is a
full TCP/IP networking stack between Squid and ICAP server doing things
to the packets. All localhost removes is the potential problems due to
differences in machine networking stacks.
Network config, firewall rules, packet handling, and/or protocol
negotiation activities between the software are all still happening that
may affect the outcome.
