The IBuySpy Portal Solution Kit demonstrates how to build a portal site using Microsoft® ASP.NET. The kit addresses modular design, caching, XML object serializing, both Microsoft Windows- and forms-based authentication, and role-based security. Windows authentication optionally uses Microsoft Active Directory® Services. Role-based security is employed to control user access to portal content.
