=head1 NAME

HTTP::Throwable::Role::Status::Unauthorized - 401 Unauthorized

=head1 VERSION

version 0.028

=head1 DESCRIPTION

The request requires user authentication. The response MUST include a
WWW-Authenticate header field containing a challenge applicable to the
requested resource. The client MAY 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 SHOULD be presented the entity
that was given in the response, since that entity might include relevant
diagnostic information.

=head1 PERL VERSION

This library should run on perls released even a long time ago.  It should work
on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.

=head1 ATTRIBUTES

=head2 www_authenticate

This is a required string or array of string that will be used to populate
the 'WWW-Authenticate' header(s) when creating a PSGI response.
