Hi,
Usually, you set the session timeout, and you can additionally add a page header to automatically redirect the current page to a page where you clear the session right before the session timeout.
From
http://aspalliance.com/1621_Implementing_a_Session_Timeout_Page_in_ASPNET.2[
^]
namespace SessionExpirePage
{
public partial class Secure : System.Web.UI.MasterPage
{
public int SessionLengthMinutes
{
get { return Session.Timeout; }
}
public string SessionExpireDestinationUrl
{
get { return "/SessionExpired.aspx"; }
}
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
this.PageHead.Controls.Add(new LiteralControl(
String.Format("<meta http-equiv='refresh' content='{0};url={1}'>",
SessionLengthMinutes*60, SessionExpireDestinationUrl)));
}
}
}
The SessionExpireDestinationUrl should link to a page where you clear the session and any other user data.
When the refresh header expires, it will automatically redirect them to that page.
