DESCRIPTION
    This module is Catalyst authentication storage plugin that authenticates
    based on a URL HTTP HEAD fetch using the supplied credentials. If the
    fetch succeeds then the authentication succeeds.

    LWP::UserAgent is used to fetch the URL which requires authentication,
    so any authentication method supported by that module can be used.

    Remote authentication methods known to work are:-

    *   Basic

    *   Digest

    *   NTLM - but see notes below

    This is re-implementation of
    Catalyst::Plugin::Authentication::Basic::Remote.

CONFIGURATION
    Configuration is done in the standard Catalyst fashion. All
    configuration keys are under "authentication/http".

    The supported keys are:-

    auth_url
        The URL that is fetched to demonstrate that the supplied credentials
        work. This can be any URL that LWP::UserAgent will support and that
        will support a "HEAD" method. This item must be supplied.

    keep_alive
        A boolean value that sets whether keep alive is used on the URL
        fetch. This must be set for NTLM authentication - and the *ntlm*
        configuration key forces it to be set.

    domain
        An optional domain value for authentication. If set the presented
        username for authentication has this domain prepended to it - this
        is really of use only for NTLM authentication mode.

    ntlm
        A boolean value that should be set if NTLM authentication is
        required. If this is set then *domain* must be set and *keep_alive*
        is forced on.

EXTENDED METHODS
  setup
    Checks the configuration information and sets up the
    "default_auth_store". This method is not intended to be called directly
    by user code.
