Naaaa....  Make your life way simpler:

var HTTP_PORTS 80
include web-<bleh>.rules
var HTTP_PORTS 8080
include web-<bleh>.rules
.
.
.


Just redefine HTTP_PORTS with one port for each of the 5 ports you want to use
for now.

Port lists are in the works...  :)  Until then, this ugly hack will have to
work.  :-/

Cheers!
