title: WCF WebSocketService read cookies
body: <p>I have a WCF service (inheriting from WebSocketService) hosted in IIS.
  I'm trying to get cookies from the request I'm handling in "OnMessage".</p>
  
  <p>I tried using:<br>
  - WebSocketContext.CookieCollection
  - HttpContext.Current.Request (Current is NULL)
  - OperationContext.Current.IncomingMessageProperties</p>
  
  <p>None of them worked.
  I'm probably missing something in the web.config file or something else.
  I'll appreciate any help.</p>
  
  <p>Thanks</p>
