This looks very easy. It seems to imply that once the client and
the server have exchanged a POST and response with no content-length
specified, they can carry on their RFB conversation without
interference from the proxy, provided the same connection
is used. I will look at adding support for this to my server
patches, once I'm sure I understand it.

Possibly the author of the Java VNC server package would like
to comment (jVNC? VNCj?).

That sounds like a good idea. I think I can handle the Win
and X servers :-) It may also make sense to add HTTP tunneling
to the native viewers, since the Java viewer is very noticably
slower.
