NCache is a clustered in-memory object cache for mission critical .NET applications. NCache also provides a highly scalable ASP.NET Clustered Session State solution for .NET applications running in server farms. Distributed caching and session state together enable you to not only speed up your .NET software by as much as 10 times but also make it more scalable and available.

NCache runs faster because unlike ASP.NET Session State that either keeps its data in SQL Server or on one computer, NCache Clustered Session State keeps it replicated on all servers in the farm. And, this also makes it more scalable because the load is not put on a single computer. And, finally, it is more reliable because there is no single-point-of-failure due to replicated clustering.
NCache as an object cache boosts .NET software performance. It not only lets you cache read-only data but also complex transactional data with relationships. NCache provides a graphical tool for configuring and monitoring clustered caches from a single computer.
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 Microsofts ASP.NET Persistent Session State.
