ACL == myport / myip

acl port8080 myport 8080
cache_peer 120.0.0.1 parent 9080 0 name=local9080
cache_peer_access local9080 allow port8080 ...

acl port8081 myport 8081
cache_peer 120.0.0.1 parent 9081 0 name=local9081
cache_peer_access local9081 allow port8081 ...

etc, etc.

For my curiosity,
  why the HTTP on different ports? squid can route internally using
cache_peer_access and vhost.
I can kind of understand the HTTPS, although singe multi-domain
certificate is simpler.
