的OutputCache属性在MVC 3被忽略 [英] OutputCache attribute being ignored in MVC 3

问题描述

所以我有IE 7的问题能够从内置的MVC 3.对于IE 7能够从一个SSL网站保存文件的SSL站点下载文件时，它必须缓存能。

So I am having an issue with IE 7 being able to download a file from an SSL site built in MVC 3. For IE 7 to be able to save a file from an SSL site, it must be cache-able.

在code的方法是：

[OutputCache(Location = OutputCacheLocation.ServerAndClient, Duration = 20, VaryByParam = "none", NoStore = true )]
public override FileContentResult Export(int? id, string extra)
{
...
return new FileContentResult(byte[], mimetype);
}

这工作在IE9，Chrome浏览器，Safari浏览器和Firefox。
我已经尝试了VaryByParam时，持续时间和NoStore各种设置。当我过任何更改这些设置响应头似乎从来没有改变。

This working in IE9, Chrome,Safari, and Firefox. I have tried various settings for VaryByParam, Duration and NoStore. When ever I change any of those settings the response headers never seem to change.

的Cache-Control：no-cache的，没有店面，必重新验证

Cache-Control:no-cache, no-store, must-revalidate

推荐答案

我解决了这个一个自己，但我离开它在那里，这样它可能是利用别人。

I solved this one myself but am leaving it out there so that it may be of use to someone else.

问题是，定制ActionFilterAttribute是手动设置缓存信息并为此我在操作设置缓存中被忽略。

The problem was that a custom ActionFilterAttribute was manually setting the cache information and therefor the caching I was setting on the Action were being ignored.

相关的属性修剪简洁：

public class CustomAttributeName: ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        var cache = filterContext.HttpContext.Response.Cache;
        cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        cache.SetValidUntilExpires(false);
        cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        cache.SetCacheability(HttpCacheability.NoCache);
        cache.SetNoStore();

        base.OnActionExecuting(filterContext);
    }
}
