<h2>Resource no longer available.</h2>
  <p>Indicates that the resource requested is no longer available and will not
    be available again. This should be used when a resource has been
    intentionally removed and the resource should be purged. Upon receiving a
    410 status code, the client should not request the resource again in the
    future. Clients such as search engines should remove the resource from their
    indices. Most use cases do not require clients and search engines to purge
    the resource, and a "404 Not Found" may be used instead.</p>
