Server Session Management

Can anyone comment as to how application servers traditionally maintain state? Is it something as simple as some in memory Map instance associating a key with perhaps another Map? And if so, what about distributed sessions...I guess either a central in-memory mechanism maintaining state across all servers in a cluster (a database even)? Just curious as to whether or not anyone out there has been on a team *writing* an application server and how state was managed.
Thanks,
Cory

I described the older (still used, but no longer the only) mechanism in WebSphere in this article.
