Out of the box, Apache-based mod_proxy servers permit CONNECT to port 443 and 563 *only*, but can add additional ports or deny even those ports. In my limited experience, almost *all* other firewall proxy servers I've encountered seem to permit any-host/any-port from inside, either through a bad default configuration, or perhaps bungling by the admins. Kudos to Apache for getting it right again. -- Randal L.
