code: public static void setScopedSessionAttr( String attrName, Object val, HttpServletRequest request )
      {
          request.getSession().setAttribute( getScopedSessionAttrName( attrName, request ), val );
      }
docs: If the request is a ScopedRequest, this sets an attribute whose name is scoped to that request's scope-ID;
  otherwise, it is a straight passthrough to {@link HttpSession#setAttribute}.
