         "Custom Outbound Header"
     Console.ForegroundColor = ConsoleColor.Red;
     Console.ForegroundColor = ConsoleColor.Blue;
     OperationContext.Current.GetCallbackChannel<IClientCallbackContract>().PushBack("Here's something to examine in response.");

   void WriteHeaders(MessageHeaders headers)
     Console.ForegroundColor = ConsoleColor.Red;
     Console.ForegroundColor = ConsoleColor.Blue;
     foreach (MessageHeaderInfo h in headers)
       if (!h.Actor.Equals(String.Empty))
         Console.WriteLine("\t" + h.Actor);
       Console.ForegroundColor = ConsoleColor.White;
       Console.WriteLine("\t" + h.Name);
       Console.ForegroundColor = ConsoleColor.Blue;
       Console.WriteLine("\t" + h.Namespace);
       Console.WriteLine("\t" + h.Relay);
