Question

I want my web page to close when SessionState timeout occures. This is my code in my web config:

<system.web>
<sessionState timeout="1" mode="InProc"/>
</system.web>

I set to 1 minute for testing purposes. The following is my Global.asax code:

protected void Session_End(object sender, EventArgs e)
{
    Response.Redirect("~/LogOut.aspx");
}

I put a label on one of the pages in order to check the session timeout, this is the code in the Page_Load event:

lblSession.Text = "SESSION TIME: " + Session.Timeout.ToString();

When I enter the site and come to this page the label shows SESSION TIME: 1, but after 1 minute I don’t get redirected to the LogOut page and the present page is still fully active and working, apparently meaning that the session has not been terminated.
I am working in Visual Studio 2008 thru the development server so suggestions I’ve seen relating to IIS settings don’t seem to be relevant at this stage.
Please help!

HTTP is a request / response protocol. There is no persistent connection between the browser and the server. The code in Session_End thus effectively does nothing — it can’t tell the browser to do anything.

You would need to make a (client-side) JavaScript timer and actively load the logout page right before the session timeout elapses.
