    If you are trying to stop the session from timeing out all the time you can do this rather than increasing the session timeout.

    KeepAlive.aspx

    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="KeepAlive.aspx.cs" Inherits="Pages.KeepAlive" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<%@ OutputCache Location="None" VaryByParam="None" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    KEEP ALIVE
    </div>
    </form>
</body>
</html>

    Keep Alive.aspx.cs

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Pages
{
    /// <summary>
    /// Page to keep the session alive
    /// </summary>
    public partial class KeepAlive : System.Web.UI.Page
    {
        //- EVENTS ------------------------------------------------------------------------------------------------------------------

        #region Events

        /// <summary>
        /// Page Load
        /// </summary>
        /// <param name="sender">object</param>
        /// <param name="e">args</param>
        protected void Page_Load(object sender, EventArgs e)
        {
            try
            {
                //Add refresh header to refresh the page 60 seconds before session timeout
                Response.AddHeader("Refresh", Convert.ToString((Session.Timeout * 60) - 60));
            }
            catch (Exception)
            {
                throw;
            }
        }

        #endregion Events

        //---------------------------------------------------------------------------------------------------------------------------
    }
}

    Then in your master page create an iFrame that refreshes to keep the session alive

    <iframe id="Defib" src="KeepAlive.aspx" frameborder="0" width="0" height="0" runat="server">
</iframe>
