Provided the requested object (not "page") is cached by Squid the
second client should be served a HIT.

If the second client TCP connection is going to some other IP address

on whether the client encounters a bug we have not yet resolved.

ETag will only help if it is presented the same by all origin servers
of the domain, and only in the cases of revalidation.
