NCache provides the following features:
1. Single-server or clustered server-farm configurations
2. Fully supports ASP.NET 2.0 Cache API
3. Read-through, write-through, and write-behind operations
4. Object relationship handling through intelligent dependency
management
5. Cache clustering as Replicated Cache, Partitioned Cache, or Near
Cache
NCache also includes a Clustered Session State for ASP.NET that lets
you use sessions in server-farms without fearing single-point of
failure and slow performance of Microsoft's ASP.NET Persistent
Session State.
