Once the request is inside a reverse-proxy it does not matter if it is
HTTP or HTTPS, the encryption stops at the receiving https_port. If you
really need to make decisions based on received protocol type you can
configure an ACL (acl HTTPS proto HTTPS) and use "HTTPS" in your access
controls as needed.

Sure it is. The classic example as in:
   http://wiki.squid-cache.org/ConfigExamples/Reverse/MultipleWebservers

using path details to decide between peers is shown at the end of the
page under "Other Criteria than Domain". How to add the HTTPS acl
mentioned above should be obvious.

There is a full config example with the specific details for setting up
OWA as a peer server at
http://wiki.squid-cache.org/ConfigExamples/Reverse/OutlookWebAccess.
Exchange is somewhat delicate in what it expects and can handle, so be
very careful about changing details on the cache_peer line from what is
shown in the example.
