This article demonstrates how to implement fragment caching in ASP.NET. Fragment caching does not actually cache a Web Form's code fragments directly; fragment caching refers to the caching of individual user controls (.ascx) within a Web Form. Each user control can have independent cache durations and implementations of how the caching behavior is to be applied. The sample code in this article illustrates how to achieve this functionality. Fragment caching is useful when you need to cache only a subset of a page. Navigation bars, header, and footers are good candidates for fragment caching.
