You are right, this is incorrect. I've been trying to fix this a number 
of times, but Mark has been afraid that we would break something by 
going to www-auth.

My position is that we break more by using Proxy-auth... As an endpoint, 
we should only use www-auth to enable an additional auth by proxy-auth 
in the same transaction.
