How to auto logout regardless of Activity

Hold on, the whole idea of session timeout is to end the session once there is no activity. Or do you want to expire the session after a certain time user has spent on your page/website?

Anyways, Look at the following links for inspiration to show timer on your webpage.

Have a look on Alert Session Time out in ASP.NET[^]

Here is the complete solution,

1. You have to set the session timeout in web.config
2. In page load, add the code below
3. Add the client side cod to popup the alert

protected void Page_Load(object sender, EventArgs e)
{
        int SessionTimeout = Session.Timeout;
        StringBuilder d = new StringBuilder();

        d.Append("<script language='javascript'>\n");
        d.Append("function BeforeTimeout()\n{\n");
        d.Append("setTimeout('CheckSession()',60000*" + ")\n}\n");
        d.Append("\n");
        d.Append("function CheckSession()\n{\n");
        d.Append("doLogout();\n}");
        d.Append("window.onload=BeforeTimeout; \n");
        d.Append("</script>\n");

        Page.ClientScript.RegisterStartupScript(typeof(Page), "key1", d.ToString());
}

client side

function doLogout(){
   //call ajax to fire server side method
   //in server side methid - remove all session and redirect to login page
}

Hope this helps.
cheers
