Yes. Exchange OWA needs the external port to be the same as the internal
port. The only exception is if using an SSL frontend then 443 may be
used externally even if 80 is used internally.

You can't. But you can make Squid listen on port 81 as well, or change
Exchange to use port 80..

Thats multipel cache_peer lines (one per web server port) and matching
cache_peer_access lines telling what may be sent to each.

But beware of the port problem mentioned above.. which depending on the
server may also be seen in the host component...

Remapping URLs to other URLs in the proxy is very likely to cause
problems. The best is if the requested URL can be forwarded as-is to the
selected server.

Note: You can select which server to forward to based on anything in the
URL, and I really mean anything. Doing it based on host name is the
simplest, but anything works.
