ASP.NET Push Redirect to a page on Session Timeout

 Usually we have some problem with the session timed out period and redirect the response to a page which will indicate user.

   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.

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.
