IIS 8, also included, is not well documented

I would assume that the web server IIS 8, that comes with Windows 8, is not much documented simply because this is not a major upgrade, but a minor one from version 7.5 already in Windows 7 Ultimate and certainly in Windows Server 2008 R2. The official IIS site takes you on a review of the main features and tools of this very mature web server: ASP.NET and PHP support, modularity and extensibility, integrated media platform, centralized web farm management, delegated remote management, versatile admin tools, dynamic caching and compression, enhanced server protection, among others.
