If the user log out from a browser and try the address does it still have access and does he is properly logged out?

Yes if He Logout also he can access the page using url

Well, if you use a computer onto which the user has never logged in, does he have access to those pages?

Either you don't properly clear information when a user log out or you don't properly control access to pages that should be protected.

Without seeing anything you have done, who knows what is going on. Now, in the same browser, IE for example, some of the same tabs use the same process so it is perfectly normal to still be authenticated because the session is still the same. But if they are opening a different browser, such as then firefox, and can get to it you are not implementing authentication properly.

No, we can't change how the internet works, or how your browser works. If what you wanted were to work, then all popups would not work, as a result.

My understanding is that you need the user to access the page only when he is logged in. IF he is not logged in but only has the URL to the page(which he might have copied earlier then he should not be able to see this page)

If my understanding is correct then what you need is either the asp.net membership and roles functionality or custom forms authentication.
