And also there is no guaranty that objects will not be removed before their expiration times as ASP.NET remove items from cache when the amount of available memory gets small. This process is called as Scavenging.
3	The session state can be kept external (state server, SQL server) and shared between several instances of our web app (for load balancing).	This is not the case with the cache.
