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.
