C#清除页面缓存

        public void SetPageNoCache()

        {

            Response.Buffer = true;

            Response.ExpiresAbsolute = System.DateTime.Now.AddSeconds(-1);

            Response.Expires = 0;

            Response.CacheControl = "no-cache";

            Response.AddHeader("Pragma", "No-Cache");

        }

    (1)   Response.Buffer = true;

            Response.ExpiresAbsolute = System.DateTime.Now.AddSeconds(-1);

            Response.Expires = 0;

            Response.CacheControl = "no-cache";

            Response.AddHeader("Pragma", "No-Cache");

    (2) HTML页面

        <meta http-equiv="Pragma" content="no-cache">

        <meta http-equiv="Cache-Control" content="no-cache">

        <meta http-equiv="Expires" content="0">

    (3) 重新调用原页面的时候在给页面传一个参数:    href="xxx.aspx?random()"
