title: WCF RoutingService - redirect with query string
body: <p>We are working on <code>WCF</code> Routing Service which redirects different <code>soap</code> actions to different endpoints. </p>
  
  <p>We want to this service rewrite query string included in router url: <code>#router url#?param=param</code> to endpoint: <code>#endpoint url#?param=param</code>. </p>
  
  <p>Our webservices accepts query strings when call directly, this strings are visible in router (context) but on the end this strings are removed from url. </p>
  
  <p>Do you know how add this strings to the end of endpoint url in every request?</p>
