      9.4 HEAD

*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.

The response to a HEAD request MAY be cacheable in the sense that the
information contained in the response MAY be used to update a previously
cached entity from that resource. If the new field values indicate that
the cached entity differs from the current entity (as would be indicated
by a change in Content-Length, Content-MD5, ETag or Last-Modified), then
the cache MUST treat the cache entry as stale.
