FastCGI: Robust and High Performance PHP with IIS
This is a guide to using and installing FastCGI, IIS and PHP. The recommended way to run stable PHP applications in IIS is CGI. But since a new process is created for each request and thrown away when the request is done, CGI efficiency is poor. Furthermore the PHP ISAPI dll was never stable enough for my needs, because ISAPI requires thread-safety, but many PHP extensions are not thread-safe.
