Are you interested in a web server for Common Lisp? We have had these for years, for example Hunchentoot. This is a standalone web server, doesn't need to be connected to any other server. No need for Apache.

Take a look at the "lack" and "Clack" packages for Common Lisp by Eitaro Fukamachi; they provide a layer of abstraction so your program thinks it has a web server, but in production it can be run by various Lisp web servers (i.e. Hunchentoot) without changes to your code.

Hunchentoot is a web server. It's a replacement for Apache.

I usually run nginx as a front-end because it's faster at serving static content and it provides some security benefits, but it's not necessary.
