title: Flash in Firefox does not send the HTTP REFERER value
body: <p>In IE and Chrome, if your swf object requests a url (mp3 file for example) it will also pass the HTTP_REFERER in the request.
  The HTTP_REFERER will be the url of the swf object.</p>
  
  <p>This does not happen in Firefox. The HTTP_REQUEST is always empty.</p>
  
  <p>Is this some option in the swf code, bug in flash or limitation of the browser?
  And is there a way to overcome this?</p>
  
  <p>Thanks in advance.</p>
