I am using global.asax on Umbraco 8.4-rc (just updated) and it seems like it's not triggering "Session_Start" when I go to the website.

protected void Session_Start(object sender, EventArgs e)
    {
        Session["Date"] = DateTime.Today.Year.ToString() + "-" + DateTime.Today.Month.ToString() + "-" + DateTime.Today.Day.ToString();
        Session["Date1"] = DateTime.Today.Year.ToString() + "-" + DateTime.Today.Month.ToString() + "-" + DateTime.Today.Day.ToString();
        Session["Date2"] = DateTime.Today.Year.ToString() + "-" + DateTime.Today.Month.ToString() + "-" + DateTime.Today.Day.ToString();
        LoadList();
        GC.Collect();
    }

Sessions are not being set and function is not being called, reason why I suspect it's not calling "Session_Start"
