25. Optimize Application and Session State Management Application State – This is information that applies to all clients of the Web application. This information is shared by, and managed for, multiple clients. Session State – This is information that applies to a specific client session. You manage this information for individual clients.

27. Optimize Application and Session State Management (Continue…) Choosing the right ASP.NET State Management Option – Session State: Does the application require centralized session state management, or can it be managed on individual Web servers? Does the application require cookie-based or cookieless session state? What kind of information needs to be stored? Does the application really need a Session object for all information? – Application State: Does the application require permanent application state? Does the application require transient application state? How frequently will stored items be updated? Does the client need direct access to the item?
