asp.net mvc浏览器缓存和压缩的实现

cache在开发高可扩展性的web应用中起着至关重要的作用，我们可以按照预定的时间将任何get请求缓存到浏览器中，如果在预定的时间内用户请求同一URL那么response就会通过浏览器的cache来实现而非server。可以通过下面的action filter在ASP.NET MVC应用中实现同样的功能：
using System;
using System.Web;
using System.Web.Mvc;
public class CacheFilterAttribute: ActionFilterAttribute
{
        /// <summary>
       /// Get or sets the cache duration in seconds . the default is 10 seconds
       /// </summary>
       /// <value> the cache duration in seconds </value>
    
      public int Duration
      {
              get;
              set;
      }
      public CacheFilterAttribute()
      {
              Duration = 10;
       }
       public override void OnActionExecuted(FiterExecutedContext filterContext)
       {
              if (Duration <= 0) return;
             
              HttpCachePolicy cache = fiterContext.HttpContext.Response.Cache;
              TimeSpan cacheDuration = TimeSpan.fromSeconds(Duration);
