Appendix A. ASP.NET and IIS 7.x

Starting with IIS 7.0, which is included in Windows Server 2008 and Windows Vista, .NET Framework became part of the web server, using a new architecture that enables direct execution of managed code. IIS 7.0 introduced a new pipeline called an integrated pipeline, which treats ASP.NET modules the same way IIS 6.0 treats native ones. You can write your own extensions to web server request and response handling using the same model that ASP.NET uses for HttpModules, and you can apply them to all kinds of requests, not only ASP.NET ones.

This appendix will analyze how to extend IIS and how to integrate it with ASP.NET.
