Extending IIS 7.5 with Modules and Handlers

IIS 7 has broken down the monolithic web server into 40 pieces. This allows web servers to be configured with what they actually need, which decreases security risks and reduces memory footprint. This architecture allows us to replace existing functionality with our own implementations. HttpModules support and HttpHandlers allows the web server to run using managed.NET code, rather than the old ISAPI technology that required unmanaged C++ or C++. New diagnostic tools allow for the saving of information about failed requests, inspection of worker processes, and active requests in the web server. The Microsoft.Web.Administration can also be used to write managed code that can create IIS web sites, application pools, or virtual directories.
