Configuration inheritance under ASP .NET Notice that this site has a subdirectory named SiteAdmin that contains its own unique configuration file, while the site as a whole is configured using the settings found within the root level web.config file. The idea (as you may suspect) is that access to SiteAdmin is more restrictive than the than of the root directory s content, and is, therefore, constrained using custom configuration settings. Copy the previous example, SecurityRoles, to a new web site called SitePersonalization. Set Welcome.aspx as the start page and run it to make sure everything still works.
