Connection oriented authentication requires support in the base HTTP
specs for such schemes, as it has far going implications on transport
and message requirements.
[Paul Leach] Since I think people safely use it today, I don't think any
additions are needed. At least when no proxy server is involved -- I
forget the trick used to make sure that proxies preserve connection
semantics before relying on Kerb/SPNEGO when using a proxy. It may be
that they won't be used if a proxy is involved.

Would be more fruitful to rework NTLM/Negotiate to fit in the HTTP
message model I think, operating somewhat similar in principle (but
obviously not algorithm) to Digest MD5-sess with a virtual session
identifier separate from the transport connection.
[Paul Leach] That was what my second suggestion from the message, part
of which you quoted above, was about. I guess it wasn't clear enough. 

It would be a better approach, but it would still be pretty helpful to
tell people how to interop with the existing approach.
