<http://trac.tools.ietf.org/wg/httpbis/trac/ticket/78>

Proposal:

1) Clarify that WWW-Authenticate can appear on any response, and that when it appears on any other than a 401, it means that the client can optionally present the request again with a credential.

and,

2) Clarify that an Authentication scheme that uses WWW-Authenticate and/or 401 MUST use the Authorization header in the request, because of its implications for caching. Schemes MAY specify additional headers to be used alongside it.
