ASP.NET MVC OutputCache 不适用于根 URI [英] ASP.NET MVC OutputCache doesn't work for root URI

问题描述

我正在学习 ASP.NET MVC，但被一个问题困扰.

I'm learning ASP.NET MVC and bugged by one issue.

在 HomeController 中，Index action 有 OutputCache 属性，但似乎不起作用.

In the HomeController, the Index action has OutputCache attribute, but it seems doesn't work.

[HandleError]
public class HomeController : Controller
{
    [OutputCache(Duration=5, VaryByParam="none")]
    public ActionResult Index()
    {
        ViewData["Title"] = "Home Page" + DateTime.Now;
        ViewData["Message"] = "Welcome to ASP.NET MVC! " + DateTime.Now;

        return View();
    }
}

尝试了好几分钟后，我发现这是由于我访问操作的方式造成的.如果我通过http://localhost:3573/"访问它，输出缓存不起作用.但是，如果我使用http://localhost:3575/Home/Index"访问它，则输出缓存有效.

After quite a few minutes trying, I found that it is due to the way I access the action. If I access it through "http://localhost:3573/", the outputcache doesn't work. However, if I access it with "http://localhost:3575/Home/Index", the outputcache works.

有人知道使默认控制器操作输出可缓存的任何解决方法吗?

Anybody know any workaround to make the default controller-action outputcacheable?

谢谢.
