Pi-Hole Lighttpd

Question

Does anyone know how I can use the pi-holes created lighttpd server with another application? I don't want to install Apache next to lighttpd... Or change the default ports.. It seems like the configuration from the pi-holes web admin in lighttpd is using lighttpd exclusively?
