Public Extensibility Features
The flexible, extensible architecture of IIS 7.0 presents developers with new opportunities for customizing the Web server. The core Web server features of IIS 7.0 have been built using a new set of public Web server APIs that all developers can use to extend, replace, or add functionality to the Web server. These APIs are available as native Win32 APIs as well as managed .NET Framework APIs. Developers can also take advantage of IIS 7.0 extensibility, with event logging, configuration, and administration tool feature sets, providing a smooth experience for customers using third-party extensions.
Build Any Feature, Any Application, Your Way.
If you want to add professional features to the base functionality provided by Windows Server 2008, you can build them utilizing either managed or native code. Windows Server 2008 provides a powerful extensibility model that allows you to support custom scenarios not supported out-of-the-box. For example, you could build a module that adds a 2-pane HTML frame for a demo version of your application in which one pane displays instructions and the other pane displays the application. Or you could build a module to rewrite or shorten URLs. And given the modular architecture of IIS 7, any extension you build can be enabled only in the sites that require it. You are not limited to only adding new features. The extensibility API lives up to its name and allows you to extend or even replace out-of-the-box modules.
