The OutputCacheSettingsSection.OutputCacheProfiles property allows you to programmatically access the outputCacheProfiles element in a configuration file. You can use the OutputCacheSettingsSection.OutputCacheProfiles property to modify the outputCacheProfiles element programmatically.

The outputCacheProfiles section contains System.Web.Configuration.OutputCacheProfile objects that represent output cache settings that may be used by pages in the application. These settings can be applied to a page by setting the CacheProfile attribute of the @ OutputCache directive. Apply the profile to control caching attributes such as dependencies, cache location, and cache expiration time.

The @ OutputCache directive can override all the settings contained by an System.Web.Configuration.OutputCacheProfile except the OutputCacheProfile.Enabled property. This is to ensure you can enable or disable the System.Web.Configuration.OutputCacheProfile without having to modify the directives in all the pages that might have overridden it.
