Whether you use PHP, Python, or any other CGI application, you should now have a clear idea of how to get your scripts processed behind Nginx. There are all sorts of implementations on the web for mainstream programming languages and the FastCGI protocol. Due to its efficiency, it is starting to replace server-integrated solutions such as Apache's mod_php, mod_wsgi, among others.
If you are unsure about connecting Nginx directly to those server applications, because you already have a well-functioning system architecture in place (for example, Apache with mod_php), you may want to consider the option offered in chapter 7, Running Nginx and Apache together.
