Question

我能够适当地利用ASP.NET MVC4 OutputCache ，并将以下代码作为Controller的索引（）的一个属性：

[OutputCache(Duration = 600, VaryByParam = "none")]

然而，

要管理不同的缓存方案，根据 the MSDN documentation ，我们可以使用 OutputCache缓存（例如）我们的控制器Index（）方法 即可。在文档之后，我们最终得到以下代码：

我们的控制器中的

    //[OutputCache(Duration = 600, VaryByParam = "none")] //works without any modification to the Web.config
    [OutputCache(CacheProfile = "Cache1Hour", VaryByParam = "none")]
    public ActionResult Index()
    {
        return View();
    }

和 在我们的Web.config

中

  <system.web>
    <caching>
      <outputCacheSettings>
          <outputCacheProfiles>
              <add name="Cache1Hour" duration="3600"/>
          </outputCacheProfiles>
      </outputCacheSettings>
    </caching>
            ...
            ...
            ...
  </system.web>

问题/问题： 显然我错过了一些东西，因为我不断抛出以下异常：

异常详细信息：System.Web.HttpException：未定义“Cache1Hour”缓存配置文件。请在配置文件中定义它。

完全例外：

Server Error in '/' Application.
The 'Cache1Hour' cache profile is not defined.  Please define it in the configuration file.

我发现我将配置代码放在'View's'Web.config而不是根Web.config中。我放置后：

<system.web>
    <caching>
      <outputCacheSettings>
          <outputCacheProfiles>
              <add name="Cache1Hour" duration="3600"/>
          </outputCacheProfiles>
      </outputCacheSettings>
    </caching>
    ...
    ...
    ...
</system.web>

...进入正确的Web.config方法被正确缓存，我希望这有助于其他人。如果没有别的，我在这篇文章中显示的代码和策略为您提供了使用OutputCache在控制器中缓存方法的最低要求。
