You can set up a Clojure/Java HTTP server (Jetty, etc.) running on some port, then use Apache's mod_proxy to forward certain requests from Apache to Clojure on that port. Something like this in your Apache configs:
ProxyPass /static ! ProxyPass /cgi-bin ! ProxyPass / http://localhost:8080/ ProxyPassReverse / http://localhost:8080/So Apache will send every request to your Clojure app on port 8080 except requests to things in /static and /cgi-bin, which Apache will handle itself.
