使用follwing code在prerender（）事件。它为我工作。

Use follwing code in OnPrerender() event of home page . It worked for me.

  protected override void OnPreRender(EventArgs e)
        {
            base.OnPreRender(e);
            string sb;
            sb = "<script language=javascript>\n";
            sb += "window.history.forward(1);\n";
            sb += "\n</script>";
            ClientScript.RegisterClientScriptBlock(Page.GetType(), "clientScript", sb);
        }
