Windows SharePoint Services 3.0 integration with ASP.NET 2.0 has been completely redesigned. First, Windows SharePoint Services 3.0 is built on ASP.NET 2.0, which provides significant enhancements over ASP.NET 1.1. Furthermore, the routing infrastructure was improved by removing the ISAPI filter and by adding an HttpModule and an HttpHandler that are registered with ASP.NET using entries in the web.config file.
