Using (Fast)CGI for non-PHP websites
From ULYSSIS documentation
You're not stuck with PHP if you want to make a dynamic website. You can use all sorts of frameworks and programming languages with ULYSSIS, as long as it has CGI or FastCGI support.
If you want to use a certain programming language or framework, and you can't get it to work, don't hesitate to contact us at ulyssis@ulyssis.org.
CGI
CGI is a very easy and simple way to create a dynamic website. We use Apache's mod_cgid to provide support for CGI.
FastCGI
We use Apache's mod_fcgid to provide support for FastCGI.
