The OPTIONS method represents a request for information about the communication options available on the request/response chain identified by the request URL. 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.

Typically the options method is used to determine what methods are supported by the server, and this is accomodated by the getAllowedMethods function.

None.

The options method is defined in section 9.2 of RFC2616.
