36/**
37 * HTTP HEAD method.
38 * <p>
39 * The HTTP HEAD method is defined in section 9.4 of
40 * <a href="http://www.ietf.org/rfc/rfc2616.txt">RFC2616</a>:
41 * <blockquote>
42 * The HEAD method is identical to GET except that the server MUST NOT
43 * return a message-body in the response. The metainformation contained
44 * in the HTTP headers in response to a HEAD request SHOULD be identical
45 * to the information sent in response to a GET request. This method can
46 * be used for obtaining metainformation about the entity implied by the
47 * request without transferring the entity-body itself. This method is
48 * often used for testing hypertext links for validity, accessibility,
49 * and recent modification.
50 * </blockquote>
