public class OptionsMethod
extends HttpMethodBase

Implements the HTTP OPTIONS method.

The HTTP OPTIONS method is defined in section 9.2 of RFC2616:

The OPTIONS method represents a request for information about the communication options available on the request/response chain identified by the Request-URI. This method allows the client to determine the options and/or requirements associated with a resource, or the capabilities of a server, without implying a resource action or initiating a resource retrieval.
