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