Flexible authentication solution for Rails with Warden.

Devise::FailureApp#http_auth?

Choose whether we should respond in a http authentication fashion,
including 401 and optional headers.

This method allows the user to explicitly disable http authentication
on ajax requests in case they want to redirect on failures instead of
handling the errors on their own. This is useful in case your ajax API
is the same as your public API and uses a format like JSON (so you
cannot mark JSON as a navigational format).
