    A View for processing DELETE requests

    The client sends a DELETE request to the URI of a Member Resource. If the
    deletion is successful, the server responds with a status code of 200.

    In a RESTful server DELETE does not always mean "delete a record from the
    database". See RESTful Web Services and REST in Practice books.
