.IX Header "DESCRIPTION"
The request requires user authentication. The response \s-1MUST\s0 include a
WWW-Authenticate header field containing a challenge applicable to the
requested resource. The client \s-1MAY\s0 repeat the request with a suitable
Authorization header field. If the request already included Authorization
credentials, then the 401 response indicates that authorization has been
refused for those credentials. If the 401 response contains the same
challenge as the prior response, and the user agent has already attempted
authentication at least once, then the user \s-1SHOULD\s0 be presented the entity
that was given in the response, since that entity might include relevant
diagnostic information.
