    1.46 + * <p>
    1.47 + * The HTTP OPTIONS method is defined in section 9.2 of
    1.48 + * <a href="http://www.ietf.org/rfc/rfc2616.txt">RFC2616</a>:
    1.49 + * <blockquote>
    1.50 + *  The OPTIONS method represents a request for information about the
    1.51 + *  communication options available on the request/response chain
    1.52 + *  identified by the Request-URI. This method allows the client to
    1.53 + *  determine the options and/or requirements associated with a resource,
    1.54 + *  or the capabilities of a server, without implying a resource action
    1.55 + *  or initiating a resource retrieval.
    1.56 + * </blockquote>
