ASP.NET 4 Unleashed

Using Data Caching

Behind the scenes, all the various caching mechanisms included in ASP.NET Framework use the Cache object. In other words, the Cache object is the fundamental mechanism for all caching in ASP.NET Framework.

One instance of the Cache object is created for each ASP.NET application. Any items you add to the cache can be accessed by any other page, control, or component contained in the same application (virtual directory).

In this section, you learn how to use the properties and methods of the Cache object. You learn how to add items to the cache, set cache expiration policies, and create cache item dependencies.
