  boolean destroyed = getSessionContext().destroy(session);
  SessionHolder.clear();
  RequestScopedCache.endRequest();
  if (destroyed) {
    // we are outside of a request (the session timed out) and therefore the session was destroyed immediately
    // we can fire the @Destroyed(SessionScoped.class) event immediately
    sessionDestroyedEvent.fire(session);
  } else {
    // the old session won't be available at the time we destroy this request
    // let's store its reference until then
    if (getRequestContext() instanceof HttpRequestContextImpl) {
      HttpServletRequest request = Reflections.<HttpRequestContextImpl> cast(getRequestContext()).getHttpServletRequest();
      request.setAttribute(HTTP_SESSION, session);
