title: HttpContext.Request.UrlReferrer null when changing domain
body: <p>Hi have a website that is host on 2 servers, on in Europe for the french version of the website (.fr) and the other in the Us for the other versions (.com). When I do a RedirectResult("http://domain.fr") from my .com website in a controller, my Referrer is null is it normal?</p>
  
  <p>I think that I will have to post a querystring from a domain to an other so I will be able to know when it's comming from this site.</p>
