This article continues my series on IIS. In Part 1 of the series we went though a web server, IIS in particular, listing out all the components of IIS with the different authentication mechanisms available. In the second part of the series we saw all the new features that are currently available in IIS 6.0. This would include the different modes of operations for IIS, all the services in IIS, Application pools, etc.

In this article we are more confined to the new features of IIS 7.0. Internet Information Services (IIS) 7.0 is the Web server for Windows Vista and Windows Server 2008. Windows Server 2008 has all the IIS features that we need to host web applications on production systems. Windows Vista also has features which depend on the version. Here the IIS is built for testing the web applications. The major change in IIS 7.0 from the previous versions of IIS is the separation of individual modules. Modules are nothing but individual features of the web server. By separating the modules, the Administrator can customize the web server by adding and removing the modules. In the next section we will go thorough all the modules in detail.
