ECL in Apache: mod_ecl
Written by jjgarcia on 2010-07
Louis Höfler has created a very interesting project: a module that allows you to execute Common Lisp in your Apache web server, much like PHP and perl modules I assume
The first version of the module is available here https://sourceforge.net/projects/mod-ecl/files/
It uses ECL as embedded Common Lisp in a very simple way. I would encourage people interested in this project to research things like security and multithreading.
