I’m interested in running Lisp web applications inside of Apache web server, for example with mod_lisp or through cgi-bin, although I’d prefer the former, simply because Apache has modules for many other functions as well. Unfortunately, what documentation there is on mod_lisp isn’t step by step to get from point A to point B.
Take a look at Clack. (Caveman2 is a web framework for Common Lisp, by Eitaro ("8arrow") Fukamachi; another recent web framework is Lucerne, by Fernando Borretti ("eudoxia0"))
Caveman is built on top of Clack and I think Lucerne is, too.
Another good option is Ningle, by Eitaro, which is a really mínimal minimal set of functions and macros to create a web application. Runs on top of Clack as well.
I wasn’t aware of Hunchentoot.
