028 * Identifies a page that should only be accessed from clients on the whitelist. This is used for
029 * some built-in pages ({@link org.apache.tapestry5.corelib.pages.PageCatalog} and {@link org.apache.tapestry5.corelib.pages.ServiceStatus}),
030 * but can also be used in application pages.
031 * <p/>
032 * Tapestry does its best to make a request to a whitelist-only page that is accessed from a client not on the whitelist
033 * appear to behave as if the page does not exist at all.
