A "session" scoped bean will be instantated once for the duration of the
session. I listed a couple of reasons when a new session would be created
and thus a new instance of the bean.
You can also define a bean in a "application" scope. The ServletContext
would be used to store/retrieve the bean in this case as opposed to the
HttpSession API. This bean will persist for the duration of the context.
