Allow header

The HTTP Allow {{Glossary("response header")}} lists the set of request methods supported by a resource. This header must be sent if the server responds with a {{HTTPStatus("405", "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.
