MVC3 HttpStatusCodeResult在OnActionExecuted中不起作用

Question

我有以下代码使用新的MVC3 HttpStatusCodeResult：

  protected override void OnActionExecuted(ActionExecutedContext filterContext) {
        base.OnActionExecuted(filterContext);
        filterContext.Result = new HttpStatusCodeResult(304, "Not Modified");
  }

我仍然得到200OK，我无法弄清楚为什么。请指教。

适合我：

public class HomeController : Controller
{
    protected override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        base.OnActionExecuted(filterContext);
        filterContext.Result = new HttpStatusCodeResult(304, "Not Modified");
    }

    public ActionResult Index()
    {
        return View();
    }
}

结果就是我们所期望的：
