| 44 * The HTTP OPTIONS method is defined in section 9.2 of | |

| 46 * <blockquote> | |
| 47 * The OPTIONS method represents a request for information about the | |
| 48 * communication options available on the request/response chain | |
| 49 * identified by the Request-URI. This method allows the client to | |
| 50 * determine the options and/or requirements associated with a resource, | |
| 51 * or the capabilities of a server, without implying a resource action | |
| 52 * or initiating a resource retrieval. | |
