This one-liner in you Apache httpd.conf file allows you to run both the Apache Web server and Domino on the same...
system - and have all your requests (be it for html or nsfs) received on port 80.
The Apache server should run on port 80, and the Domino server on some other port (10080 in this code example)
#Redirect all nsfs to Domino HTTP Server on port 10080 RedirectMatch /(.*).(nsf)(.*) http://localhost:10080/$1.$2$3
