As traffic grows to a data-driven site, the demands placed on the Web server and database server increase rather quickly. If, for a given Web page, each page request requires a trip to the database, you may soon find your site's performance far below par. If that given page is showing data that changes infrequently, you can cache the information to save on round trips to the database server!
Below you will find a number of links to various articles and components you can use to enable caching on your ASP site! With large, busy, data-driven sites there are oftentimes two options: either write code that caches frequently requested data or simply keep packing on extra database servers and Web servers. For those of us who can't afford to pour gobs of money into our sites, caching is the only viable alternative!

Caching with ASP.NET
ASP.NET offers a multitude of caching options, including caching of a Web page's HTML output (Output Caching), caching the HTML output of a fragment of a page (Fragment Caching) and using a rich caching API to cache objects (such as DataSets; called Data Caching).
