Unfortunately, the nature of ASP.NET means that you cannot tell if a user is logged in already. Sure you can log the fact a user has accessed your application, but there is no way to tell that they have abandoned their old session, perhaps by closing their browser, and that their new login is therefore valid.
you have to implement your own method
