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 %>
