By default, the System.Web.XmlSiteMapProvider object is used and site navigation data is loaded from the Web.sitemap file that is located in the root directory of the site. This is identified in the management classes that manage the site navigation configuration and the site map configuration section of the Web.config files. By default, it is an instance of the System.Web.XmlSiteMapProvider class, which uses the Web.sitemap file as its persistent store. However, you can implement your own site map storage and configuration scheme by writing a class that implements the abstract System.Web.SiteMapProvider class. For more information on writing your own provider, see System.Web.SiteMapProvider.
