     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.
