This is the solution I found on Coding Solutions

in the master page

    protected void Page_Load(object sender, EventArgs e)
    {
        Response.ClearHeaders();
        Response.AppendHeader("Cache-Control", "no-cache"); //HTTP 1.1
        Response.AppendHeader("Cache-Control", "private"); // HTTP 1.1
        Response.AppendHeader("Cache-Control", "no-store"); // HTTP 1.1
        Response.AppendHeader("Cache-Control", "must-revalidate"); // HTTP 1.1
        Response.AppendHeader("Cache-Control", "max-stale=0"); // HTTP 1.1
        Response.AppendHeader("Cache-Control", "post-check=0"); // HTTP 1.1
        Response.AppendHeader("Cache-Control", "pre-check=0"); // HTTP 1.1
        Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.1
        Response.AppendHeader("Keep-Alive", "timeout=3, max=993"); // HTTP 1.1
        Response.AppendHeader("Expires", "Mon, 26 Jul 1997 05:00:00 GMT"); // HTTP 1.1
    }

Control LoginStatus

    protected void LoginStatusUser_LoggedOut(object sender, EventArgs e)
    {
        Session.Abandon();
        FormsAuthentication.SignOut();
    }
