Hi.
What is the "correct" behaviour for an HTTP user agent, when it process a WWW-Authenticate header containing unsupported challenge?
I have found that Internet Explorer, Firefox, Konqueror, Epiphany, ignore the header.
Opera, however, reports an error: Error! The server requested a login authentication method that is not supported. Is this an acceptable behaviour? RFC 2616 says nothing, here. Thanks Manlio Perillo
