 * Returns a request to unconditionally validate a cache entry with the

 * may actually receive a response to a normal conditional validation where
 * the Date header is actually older than that of our current cache entry.
 * In this case, the protocol recommendation is to retry the validation and
 * force syncup with the origin.// w  ww .ja v a  2 s . c om
