    You can always make a method of the Session_Start and call it

    namespace WebFormsApplication1
    {
        public class Global : HttpApplication
        {
            void Session_Start(object sender, EventArgs e) 
            {
                Global.StartSession();
            }
        }
    
        public static class Global 
        {
            public static void StartSession() {
    
                Session["Test"] = 1;
            }
        }
    }
    

    and in your Handler, simply call Global.StartSession();

    The Session_Start event is trigerred whenever some server side handler attempts to either read or write to the session. You might try decorating your handler with the IRequiresSessionState marker interface:

    public class MyHandler: IHttpHandler, IRequiresSessionState
    {
        ...
    }
