如何清除MVC应用程序中的浏览器缓存?
问题描述:
我想清除MVC应用程序中的浏览器缓存.
I want to clear the browser cache in MVC application.
我在.cshtml页面上添加了以下代码,该代码适用于IE和Firefox.
I added the below code on my .cshtml page and its working for IE and Firefox.
Response.ExpiresAbsolute = DateTime.Now;
Response.Expires = 0;
Response.CacheControl = "no-cache";
Response.Buffer = true;
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow);
Response.Cache.SetNoStore();
Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
我正在寻找一种适用于chrome的解决方案.
I am looking for a solution which will work on chrome as well.

使用以下属性:
public class NoCacheAttribute : ActionFilterAttribute
{
public override void OnResultExecuting(ResultExecutingContext filterContext)
{
if (filterContext == null) throw new ArgumentNullException("filterContext");
var cache = GetCache(filterContext);
cache.SetExpires(DateTime.UtcNow.AddDays(-1));
cache.SetValidUntilExpires(false);
cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
cache.SetCacheability(HttpCacheability.NoCache);
cache.SetNoStore();
base.OnResultExecuting(filterContext);
}
/// <summary>
/// Get the reponse cache
/// </summary>
/// <param name="filterContext"></param>
/// <returns></returns>
protected virtual HttpCachePolicyBase GetCache(ResultExecutingContext filterContext)
{
return filterContext.HttpContext.Response.Cache;
}
}
}
只需将其添加到您的基本控制器中即可:
Simply add this to your base controller :
[NoCache]
public BaseController: Controller
