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

namespace Pages

public partial class KeepAlive : System.Web.UI.Page

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
