The HTTP Allow response header lists the set of request methods supported by a resource. This header must be sent if the server responds with a 405 Method Not Allowed status code to indicate which request methods can be used instead. An empty Allow value indicates that the resource allows no request methods, which might occur temporarily for a given resource.
