Well you probably have to hack squid for that, but the HTTP/1.1 standard
defines a Host: header so that virtual WWW servers no longer need their
own IP number, just a CNAME in the DNS will be enough (major design
flaw in the original HTTP specs).

If you could tell squid to lookup the hostname of the ip number that
getsockname() returns and add a HTTP "Host" header, apache would know
what virtual host to serve.
Apache 1.0.5 does not support this, but 1.1 is supposed to..
