    adding following code in the page load of the page for which we do not want to cache the page in history.

    [COLOR=black][COLOR=black][FONT=Arial][COLOR=black][COLOR=black][FONT=Arial][COLOR=black][COLOR=black][FONT=Arial][COLOR=black][COLOR=black][FONT=Arial][COLOR=black][FONT=Arial][COLOR=black][FONT=Arial][COLOR=black][FONT=Arial][FONT=Times New Roman][FONT=Arial][FONT=Arial][FONT=Arial][FONT=Arial][FONT=Arial][FONT=Arial][FONT=Arial][FONT=Arial][FONT=Arial]Response.Buffer=<SPAN style="COLOR: blue">true;<o:p></o:p>
Response.ExpiresAbsolute=DateTime.Now.AddDays(-1d);
Response.Expires =-1500;
Response.CacheControl = "no-cache";
 if(Session["SessionId"] == null)
    {
    Response.Redirect ("WdetLogin.aspx");
    }
}[/FONT][/FONT][/FONT][/FONT][/FONT][/FONT][/FONT][/FONT][/FONT][/FONT][/FONT][/COLOR][/FONT][/COLOR][/FONT][/COLOR][/FONT][/COLOR][/COLOR][/FONT][/COLOR][/COLOR][/FONT][/COLOR][/COLOR][/FONT][/COLOR][/COLOR]
    Or 

    Response.CacheControl = "no-cache";
    for session details

    when logging out you should use 
    Session.Abandon();
Session.Redirect("Login.aspx");

instead of Session["loggedIn"] = false;

    ok
    Try this java script
    <script type = "text/javascript" >
   function preventBack(){window.history.forward();}
     setTimeout("preventBack()", 0);
     window.onunload=function(){null};
 </script>

    protected void Page_Load(object sender, EventArgs e)
    {
        if (Session["CS"] != null)
        {
            con.ConnectionString = Session["CS"].ToString();
            com.Connection = con;
            Session.Add("User_Name", null);
            Session.Add("Password", null);
        }
        else
        {
            Response.Redirect("Main Home.aspx");
        }

    }
    This will be for the page users visits after looging in

    and on the click of Sign out 

      protected void logout_Click(object sender, ImageClickEventArgs e)
    {
        Session["User_Name"] = null;
        Session["Password"] = null;
        Response.Redirect("Default.aspx");
    }
    This will help you solve the problem.
    Am I right?
