如何在C＃asp.net MVC4中应用缓存 [英] How to apply Caching in C# asp.net MVC4

问题描述

我需要在我的网络应用程序中实现图像缓存，因为我的主页需要时间来加载图像。我尝试以不同的方式捕捉，但没有申请。



i添加新课程

Hi,
i need to implement Cache for Images in my web application , because my home page is taking time for loading images . i tried catching in differnt ways, but not applying.

i added new class

public class CacheFilterAttribute : ActionFilterAttribute
    {
        public int Duration
        {
        get;
        set;
        }

        public CacheFilterAttribute()
        {
        Duration = 60;
        }

        public override void OnActionExecuted(ActionExecutedContext filterContext)
        {
        if (Duration <= 0) return;

        HttpCachePolicyBase cache = filterContext.HttpContext.Response.Cache;
        TimeSpan cacheDuration = TimeSpan.FromSeconds(Duration);

        cache.SetCacheability(HttpCacheability.Public);
        cache.SetExpires(DateTime.Now.Add(cacheDuration));
        cache.SetMaxAge(cacheDuration);
        cache.AppendCacheExtension("must-revalidate, proxy-revalidate");
        }

    }

在控制器操作方法之后

after in controller Action method

[CacheFilter(Duration = 60000)]
 [OutputCache(Duration = 1800)]  //, VaryByParam = "*")
  public ActionResult Home()
 {

 }

无法正常工作，我也试过了web.config，但仍然没用。

如何进行缓存？我只需要缓存图像

not working , i tried through web.config also, but still no use.
How can i do caching ? i just need caching for images

推荐答案

尝试outputcache（location = client）

Try outputcache(location=client)

我认为你需要使用的是ASP.NET的WebCache。

您也可以在MVC应用程序中使用它因为它是ASP.NET的一部分。您也可以轻松地从缓存中添加缓存和提取。

What I think that you need to use is the ASP.NET's WebCache.

You can use it in your MVC application too since it is a part of ASP.NET. You can easily add caching and extract from the cache too.
