Windows Server 2008 R2 and IIS 7.5 Channel9 Episodes
New MSDN Channel9 episodes illustrate FastCGI, PHP, and WebDAV IIS 7.5 extension capabilities.
FastCGI is a language-independent, scalable, open extension to CGI that provides high performance. The FastCGI extension enables application frameworks such as PHP to achieve improved performance and stability on Internet Information Services. See a demo here.
The IIS WebDAV extension module incorporates new features that enable web authors to publish content easier than before, and offers web administrators more security and deployment options. See a demo here.
