        if (request.getCookies() != null) {
          Cookie[] cookies = request.getCookies();
          String loginname = null;
          for (Cookie cookie : cookies) {
            if (cookie.getName().equals("loginname")) {
              loginname = cookie.getValue();
            } 
         }
       }
