See example 8.
Basically you end up with 2 server objects in your Web server procedure, one listening on port 80 (unsecure) and one on port 443 (secure.)
But they share a common WebHandler procedure. So there's almost nothing for you to do except add the extra server object.
tip: if you have static files that must only be served over the secure connection then place them in the 'secure' folder.
tip: if you have pages that should only be viewed on the secure connection then tick on the option on the advanced tab.
