An application's Cache object allows you to store and retrieve arbitrary data on subsequent requests. The cache is not specifically associated with a page or user session. It is used primarily to enhance application performance. For more information, see Caching Application Data. For more information on the difference between application caching and page output caching, see Introduction to Caching in ASP.NET.
The following code example inserts the sum of two integers into the System.Web.Caching.Cache object using the Page.Cache property. It then retrieves the value using the System.Web.Caching.Cache.Get(System.String) method and writes it to a Label Web server control.
