Just out of curiousity - I know about the HTTP CONNECT method, but
what other methods could you use to 'abuse' squid to connect to a non-HTTP
service?

Maybe there should be an acl option that lets you specity which ports
http connect is valid on? I haven't ever seen an encrypted http session
on a port other than 443 (but its bound to exist *somewhere* I'm sure..)

Or am I off track, since this acl is in squid and I'm just not parsing
the conf file right?
