        <h2><strong>No Referer header found!</strong></h2>
        <p>
          You have requested we check the referring page, but your browser did
          not send the HTTP "Referer" header field. This can be for several
          reasons, but most commonly it is because your browser does not
          know about this header, has been configured not to send one, or is
          behind a proxy or firewall that strips it out of the request before
          it reaches us.
        </p>
        <p>This is <em>not</em> an error in the referring page!</p>
        <p>
          Please use the form interface on the
          <a href="/">Validator Home Page</a> to check the
          page by URL.
