Why not redirect all traffic that is sent directly to port 80 to a
single server giving a short message describing how to configure the
proxy settings. I think this will keep everyone happy.

* Network admins know that everything goes througth the proxy/cache.
* Users always get the information on how to configure the proxy
settings when needed.
* The support-line is not bothered with questions on how to configure
* All gain from a higher hit ratio in the caches.

For those of us that don't remember the disadvantages of transparent
* Only the IP address is known. Possible to search the request for a
Host: header but this is a bit unreliable (not much in reality).
* Only well known ports can be supported. Basically only port 80, since
other ports might be used for other protocols/services.
* The client is required to do DNS queries.
