Remarks

You should not call this method. To enable and manipulate output caching for a page, use either the @ OutputCache directive in the .aspx file, or the methods and properties of the HttpCachePolicy class. The latter are accessible through Response.Cache syntax in the page's code-declaration block or code-behind file. For more information, see Caching ASP.NET Pages.
