title: Examine http response headers in IE8
body: <p>I'm looking for an ie8-addon that displays the http headers like firebug or httpliveheaders do. Any advice is appreciated.  </p>
  
  <p>edit: I may be blind but <i>it seems</i> as if the built-in developer tools (F12) do <i>not</i> show the http headers.</p>
