Authentication is independent of the response body.
It is all done in the HTTP headers.
Nothing prevents a client to send an Authorization header without receiving a
401 response beforehand (RFC 2616, section 14.8.)
And servers are free to send multiple WWW-Authenticate headers, for each one of
the authentication schemes they support (for example, IIS can indicate support
for the custom NTLM authentication.)
So, I still fail to see what the problem is.
