MVC4中的OutputCache有问题吗？ [英] Problem with OutputCache in MVC4?

问题描述

我正在使用OutputCache在ActionMethod上缓存持续60秒的持续时间，后退项目列表。它运行正常，但问题是当我在列表中添加项目时，ActionMethod返回上一个列表，新项目未在列表中显示60秒。我如何克服这个问题？

I am using OutputCache to cache for duration like 60 sec on ActionMethod that retrun the list of item. It work fine, but the problem is when i add item in list then the ActionMethod return the previous list, the new item not shown in list for 60 sec. How i can overcome this problem?

推荐答案

public class ClearCache : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
        filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        filterContext.HttpContext.Response.Cache.SetNoStore();

        base.OnResultExecuting(filterContext);
    }
}
