I agree that it's stupid to have a special-case for CONNECT parsing, but
that's *already* how implementations are required to behave. A client
that tries to parse a CONNECT response according to the rules currently
given in RFC 2616 will be unable to create a tunnel. Requiring proxies
to add "Content-Length: 0" won't help, because clients will still want
to be able to deal with pre-2616bis proxies, which will require the
special case.
