HOW TO: Send a user to a timeout page when their session has expired using ASP.NET 2.0
ASP.NET
Are your users getting error messages when their session times out? You can easily forward your users on to a page letting them know that their session has expired and they need to begin again. The code below handles this rather gracefully:
1 void Session_Start(object sender, EventArgs e)
2 {
3 // check the header for the presence of the cookie -- if it exists then it is an expired session
4 string _cookieHeader = System.Web.HttpContext.Current.Request.Headers["Cookie"];
5 if ((null != _cookieHeader) && (_cookieHeader.IndexOf("ASP.NET_SessionId") >= 0))
6 {
7 System.Web.HttpContext.Current.Response.Redirect("/expiredSession.htm");
8 }
9 }
