Back button Issue after Logout

I have gone through some links and spend hours but My page still loads after log out on clicking back button. here is my log out page code which i tried.

protected void Page_Load(object sender, EventArgs e)
    {
    if(Session[Constants.KeyValues.UserProfileSession]== null)
     {
            Response.Redirect("www.google.com", true);
     }          

        ////Clear cookie and redirect user to login page (Landing page before login).
        Response.AddHeader("pragma", "no-cache");
        Response.AddHeader("cache-control", "private");
        Response.CacheControl = "no-cache";
        Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetNoStore();
        FormsAuthentication.SignOut();
        Response.Cookies.Clear();

        HttpContext.Current.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));

        HttpContext.Current.Response.Cache.SetValidUntilExpires(false);
        HttpContext.Current.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        HttpContext.Current.Response.Cache.SetNoStore();


        Session.Clear();
        Session.Abandon();
        Session[Constants.KeyValues.UserProfileSession] = null;            
        Response.Write("<script type=\"text/javascript\">window.location.replace('www.google.com');</script>");
        //Response.Redirect("www.google.com", true);
    }

here is my html page 

<!doctype html>
<html lang="ko">
<head>
    <title></title>
    <meta http-equiv="Cache-Control" content="no-cache" />
    <meta http-equiv="Pragma" content="no-cache" />
    <meta http-equiv="Expires" content="0" />
    <script type="text/javascript">
        function ClearHistory() {
            var backlen = history.length;
            history.go(-backlen);
            window.location.href = www.google.com
        }
    </script>
</head>

Try to use this, it works across all browsers.

    Response.AppendHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
    Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.0.
    Response.AppendHeader("Expires", "0"); // Proxies.
