Explain Fragment Caching In ASP.NET

Fragment caching is known as partial caching, that means we can easily cached the specific part of a web form.To cache a portion of a page, you must first encapsulate the portion of the page you want to cache into a user control. In the user control source file, add an OutputCache directive specifying the Duration and VaryByParam attributes. When that user control is loaded into a page at runtime, it is cached, and all subsequent pages that reference that same user control will retrieve it from the cache. For example, we might have a header for our page which will have the same content for all users.The solution is to put the header contents into a user control and then specify that the user control content should be cached. This technique is called fragment caching.To specify that a user control should be cached, we use the @OutputCache directive just like we used it for the page.

<%@ OutputCache Duration=10 VaryByParam="None" %>
