CORBA35 — Issue for Firewall RTF - HTTP tunnelling.

Summary: The submission makes no mention of HTTP tunnelling. There are many
firewalls which filter HTTP, FTP and email related traffic. Is the
omission based on the assumption that such firewalls will comprise
a CORBA conformant GIOP proxy on a well-known IIOP port? The Bi-
directional GIOP specification suggests not (section 5-1,
paragraph 2).

Is tunnelling regarded as an implementation matter? If so there
will be important issues such as relaxing GIOP/HTTP mapping and
security which the specification should clarify.
