Why an invalid session can invoke its method

[Napu Sun]

I noticed that an invalid session can invoke getServletContext() without problem. This makes me confusing what is an invalid session. Is an invalid session supposed to be collected by GC?

Thanks Guys.

The GC can't collect something that is still being referenced.

A session getting invalidated is like getting fired from your work. You haven't quite left the building (your context) yet, but you really aren't allowed to do any more work.

Hi Marc,


This is a good example....really I mean it....now I can remeber this SessionInvalid concept without any problem.

Thanks

Marc, thank you again.

So an invalid session is still alive with the reference to the context, but it is not allowed to do his work any more.

Cool example Marc!
