title: Send a location hash through a referrer
body: <p>I have a page where in Javascript I add to the location hash something like: 
  location.hash = "initial_source=previous_referrer".</p>
  
  <p>Afterwards a window.location is done in order to redirect. </p>
  
  <p>However the receiver gets the referrer in his request without the hash (#) part.</p>
  
  <p>Is it possible to somehow modify the URL in the initial page, without a redirect, so the final referrer is what is desired?</p>
  
  <p>Thank you.</p>
