Attaching events to Session OnStart and OnEnd using HttpModules

Question

Does anyone know a clean way of adding events to Session's OnStart and OnEnd events using an HttpModule (without touching the Global.asax file)?

Answer 1

public void Init(HttpApplication app)
{
   var ssm = app.Modules["Session"] as SessionStateModule;
   ssm.Start += Foo;
   ssm.End += Bar;
}
