Where is the specification that limits authentication challenges to
responses whose Status-Code is “401”? I believe that there is no such
specification. In the absence of such a specification, the use of
authentication challenges is perfectly legitimate in any response,
including a response whose Status-Code is “200”.
I gave an example of that use in “Authentication and authorization as
influences on the content of responses [foaf-dev]”
