    Detecting Session Timeout and Redirect to Login Page in ASP.NET

    HTTP(web page) is stateless, so we cannot know whether the Session has really expired without sending a page request back to the server. If you want to redirect the page immediately(with out any user action) after session expires consider this approach.

     

    Response.AppendHeader("Refresh",Convert.ToString((Session.Timeout * 60)+ 10)+";URL=Login.aspx");
    

     
    

    Add this line of code to page_Load.

    I found this code, which consists -5. Actually what is that number means and its sign?

    HttpContext.Current.Response.AppendHeader("Refresh", Convert.ToString(((HttpContext.Current.Session.Timeout * 60) - 5)) + "; Url=YOUR PAGE WHICH YOU WANT TO SHOW");

    I've had tinnitus ever since I was twelve.  Until recently though I did not know that itwas such a large problem with thousands of people until I saw somewhere that Jessica Simpson suffered from tinnitus.  I'm happy that I discovered help and products that can actually cure my tinnitus.  Thank you so much for the info!
