Comment(by zooko):

 Last year I asked Collin Jackson (who knows a good deal about web
 security) how to automatically prevent Referer Headers from being sent.
 He repied:

   Most of the techniques involve making the request come from a non-HTTP
 scheme. The browser usually won't bother to send a Referer in this case.

   Option A: ftp scheme


   Option B: about:blank scheme

   w = window.open("");
   w.document.write("<form ...>");

   Option C: javascript: scheme
