] Digest-MessageDigest has been part of the draft since its very early
] versions.  It has limitations. I don't think we are in a position
] to either remove it or overcome its limitations.  The new nextnonce
] field seems to me to be a useful addition which is is a very modest
] change and not likely to lead to any unpleasant surprises.  I also
] agree with Paul that there is not much reason to keep the user, nonce
] and realm fields.  In the fullness of time we can and will create
] stronger ways of dealing with authentication, proxies, headers, etc.
] I propose that the D-MD section of this draft be:

The problem is, this is broken when a proxy is involved.  I don't care 
if you enhance the section along the lines of my suggestions, but it 
has to work when proxies are involved, otherwise huge numbers of 
clients can't use digest auth -- perhaps even the majority of users in 
the near future.
