 * - Message body
 *
 * During construction, implementations MUST attempt to set the Host header from
 * a provided URI if no Host header is provided.

 * be implemented such that they retain the internal state of the current

   *   request.
   * - If the Host header is missing or empty, and the new URI does not contain a
   *   host component, this method MUST NOT update the Host header in the returned
   *   request.

   *   the Host header in the returned request.
