csharp ASP.net MVC：完全禁用缓存

Posted 2021-05-12

This is discouraged though. You should rely on the ASP.net caching mechanisms as described in [this article](http://juristr.com/blog/2012/10/output-caching-in-aspnet-mvc/)

public class NoCacheGlobalActionFilter : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        //IE: http://support.microsoft.com/kb/316431
        if (!(filterContext.Result is FileResult))
        {
            HttpCachePolicyBase cache = filterContext.HttpContext.Response.Cache;
            cache.SetCacheability(HttpCacheability.NoCache);
        }

        base.OnResultExecuting(filterContext);
    }
}
