Accepted answer

Hi,

Your logout link/button should point to a page containing this code, along with whatever else you want.

using System.Web.Security;

private void Page_Load(object sender, System.EventArgs e)
{
    // Put user code to initialize the page here
    Session.Abandon();
    FormsAuthentication.SignOut();
}

or 

place this in all secure pages

Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();

write these code Under:

In page load event:

    protected void Page_Load(object sender, EventArgs e)
    {
        if (Session["RefreshCtr"] == null)
        {
            Session["RefreshCtr"] = 1;
            lblRefresh.Text = Session["RefreshCtr"].ToString();
        }
        if (!IsPostBack)
        {
           //code goes here
        }
    }

In pre_render event:

    private void Page_PreRender(object sender, EventArgs e)
    {
        lblRefresh.Text = Session["RefreshCtr"].ToString();
    }

In button click event:

    protected void Button1_click(object sender, EventArgs e)
    {
        if (lblRefresh.Text == Session["RefreshCtr"].ToString())
        {
            Session["RefreshCtr"] = Session["RefreshCtr"].ToString() + 1;
        }
    }

It will works.....
