[squid-users] Checking for content on local proxies first

Even with Duane Wessel's "Squid, The Definitive Guide" as a reference, it
is a daunting task to determine which of the configuration options will
provide the behaviour that you would like to see.

   (1) I would like to have all requests for external (non-corporate)
        web content forwarded to a Squid proxy at the security boundary.
        This seems to be addressed adequately with the following.

                acl CORP dstdomain .corp.com
                never_direct allow !CORP

   (2) I would like all requests for local content to be retrieved from
        the local web server.

                acl DIV dstdomain .div.corp.com
                always_direct allow DIV

   (3) The links to other divisions are being changed from dedicated
        circuits to a dynamic VPN architecture. I would like to relay
        requests to a Squid proxy at the division where the content is.
        In the past, I have used cache_peer_domain for this.

   (4) Before performing (1) or (3), I would like to determine if a local
        Squid proxy already has a fresh copy of the requested content. It
        doesn't seem desirable to be moving content repeatedly over a link
        where the payload will be encrypted and fragmented.

Any suggestions on the "best" method of obtaining the desired behaviour?
