What new ways are there to handle session state in a web cluster?

There are two new methods of handling session state in a web cluster. The first method is to designate one server as a "state server" by enabling the state service on it. This server can then be the central store of state information for the entire cluster. Another option is to persist the state information directly to a SQL Server database. This not only gives you a shared, central store for state information but also allows you to retain state information in case of a failure or server reboot.
