System.Web.Caching Namespace

The System.Web.Caching namespace provides classes for caching frequently used data on the server. This includes the Cache class, a dictionary that allows you to store arbitrary data objects, such as hash tables and data sets. It also provides expiration functionality for those objects, and methods that allow you to add and removed the objects. You can also add the objects with a dependency upon other files or cache entries, and perform a callback to notify your application when an object is removed from the Cache.
