Yes, however -
Breaking past firewalls is actually pretty easy, assuming they allow
HTTPS access to outside world. What you do is, run server on port 443,
then connect to HTTP proxy, send:
or the appropriate syntax for the CONNECT command, and the connection
will now be opened for 443. At this point you switch to your protocol of
choice and can do whatever you want over this connection.
