For this. Yes. The rewrite (*not* redirect) is necessary to change the
path segment. The rest is normal for virtual hosting.

However, its really a bad idea to do it this way (with /path
differences) in the first place.

Ideally you have the server doing virtual hosting for the two domain
names and using port 80 as well. Squid then just passes the requests
traffic to the right server and the server itself does not then have to
care about getting port and path etc right in every URL reference the
cotent contains, just uses relative URLs. A site like that can even be
proxied for HTTPS quite easily.
