	String^ varyByCustom, 
	OutputCacheLocation location, 
	String^ varyByParam
)

Parameters

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. For more information, see Caching ASP.NET Pages.
