Gzip 壓縮不起作用 ASP.net MVC5

我想用 Gzip 壓縮我的 Web 應用程序，我正在使用以下類

壓縮過濾器

public class CompressFilter : ActionFilterAttribute
{
   public override void OnActionExecuting(ActionExecutingContext filterContext)
   {
       HttpRequestBase request = filterContext.HttpContext.Request;
       string acceptEncoding = request.Headers["Accept-Encoding"];
       if (string.IsNullOrEmpty(acceptEncoding)) return;
       acceptEncoding = acceptEncoding.ToUpperInvariant();
       HttpResponseBase response = filterContext.HttpContext.Response;
       if (acceptEncoding.Contains("GZIP"))
       {
           response.AppendHeader("Content-encoding", "gzip");
           response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);
       }
       else if (acceptEncoding.Contains("DEFLATE"))
       {
           response.AppendHeader("Content-encoding", "deflate");
           response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);
       }
   }
}

記憶體過濾器

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

   public CacheFilterAttribute()
   {
       Duration = 1;
   }

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

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

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

控制器

[CompressFilter]
[CacheFilter(Duration = 60)]
public ActionResult Index()
{}

並將此類應用於控制器中的操作。但是在螢火蟲中它仍然顯示**“Transfer-Encoding: chunked”，但它應該是“Transfer-Encoding: gzip”**。

我正在本地主機上測試它。

請告訴我我做錯了什麼？謝謝並恭祝安康。

更新記憶體過濾器工作正常，但仍然沒有 gzip 壓縮，下面是 chrome 中的響應頭。

Cache-Control:public, must-revalidate, proxy-revalidate, max-age=3600
Content-Type:text/html; charset=utf-8
Date:Wed, 22 Jul 2015 13:39:06 GMT
Expires:Wed, 22 Jul 2015 14:39:04 GMT

Transfer-Encoding:chunked

有什麼辦法可以完成這項工作，我真的需要幫助，謝謝

如果您無法控制 IIS，只需將其添加到您的 Global.ASCX。在 Android、iPhone 和大多數 PC 瀏覽器上測試。

protected void Application_BeginRequest(object sender, EventArgs e)
   {

       // Implement HTTP compression
       HttpApplication app = (HttpApplication)sender;


       // Retrieve accepted encodings
       string encodings = app.Request.Headers.Get("Accept-Encoding");
       if (encodings != null)
       {
           // Check the browser accepts deflate or gzip (deflate takes preference)
           encodings = encodings.ToLower();
           if (encodings.Contains("deflate"))
           {
               app.Response.Filter = new DeflateStream(app.Response.Filter, CompressionMode.Compress);
               app.Response.AppendHeader("Content-Encoding", "deflate");
           }
           else if (encodings.Contains("gzip"))
           {
               app.Response.Filter = new GZipStream(app.Response.Filter, CompressionMode.Compress);
               app.Response.AppendHeader("Content-Encoding", "gzip");
           }
       }
   }
