Exploring more into caching in asp.net-- Caching page fragments (Part 3)

Sometimes we might want to cache just portions of a page. For example, we might have a header for our page which will have the same content for all users. There might be some text/image in the header which might change everyday. In that case, we will want to cache this header for a duration of a day.

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" %>

With the above directive, the user control content will be cached for the time specified by the Duration attribute [10 secs]. Regardless of the querystring parameters and browser type and/or version, the same cached output is served.
