35   * HTTP PATCH method.
36   * <p>
37   * The HTTP PATCH method is defined in <a
38   * href="http://tools.ietf.org/html/rfc5789">RF5789</a>: <blockquote> The PATCH
39   * method requests that a set of changes described in the request entity be
40   * applied to the resource identified by the Request- URI. Differs from the PUT
41   * method in the way the server processes the enclosed entity to modify the
42   * resource identified by the Request-URI. In a PUT request, the enclosed entity
43   * origin server, and the client is requesting that the stored version be
44   * replaced. With PATCH, however, the enclosed entity contains a set of
45   * instructions describing how a resource currently residing on the origin
46   * server should be modified to produce a new version. </blockquote>
