The System.Web.Configuration.OutputCacheSettingsSection object refers to the outputCacheSettings section of the configuration file.

The output cache settings enable or disable disk-based persistent output cache, define the location for persisting the data to be cached, and specify the maximum size of the cache per application.

ASP.NET allows you to cache multiple versions of a page response declaratively by using attributes of the @ OutputCache directive and programmatically using the properties and methods of the System.Web.HttpCachePolicy class.

You can achieve the same results by configuring the application using the System.Web.Configuration.OutputCacheSettingsSection or the System.Web.Configuration.OutputCacheProfile type.
