Question

Here is my code:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!Session["Authenticated"] )
        {
            Response.Redirect( "index.aspx", false );
        }
    }

Once they login I set the session to true. Basically, if they don’t have an active session I want them re-directed back to the index/login page. How do I accomplish this?

Use this check

if(Session["Authenticated"] == null || !(bool)Session["Authenticated"])
