If you use ĆONNECT there is no HTTP involved other than the initial
CONNECT request to open the control channel. CONNECT in HTTP is
equivalent to CONNECT in SOCKS. It gives you a full duplex "direct"
connection to the requested server.

If you think allowing CONNECT to be used in this manner (the default
squid.conf does not for very valid security reasons) I assure you that
you would be much better off using a SOCKS proxy.

Squid does not implement the DELETE HTTP method on ftp:// URLs.

Squid does not allow CONNECT ports other than 443 (https) and 563
(snews) by default. Other ports may be allowed by the local proxy admin,
but great care should be taken in what ports you open up to not allow
abuse of the HTTP proxy service.
