Wildcard script mapping and IIS 7 integrated pipeline

The big benefit of IIS 7 integrated request processing pipeline is the fact that all the nice and useful ASP.NET features can be used for any type of content on your web site; not just for ASP.NET-specific content. For example, ASP.NET SQL-based membership can be used to protect static files and folders. Also, ASP.NET extensibility API’s, such as IHttpHandler and IHttpModule can be used to add custom modules and handlers that would be executed even for non-ASP.NET content.
