How to force response to ONLY https requests...

Hi all:

I have a Mac OS X Server set up with SSL, and a deployed WO application - connecting through "https://..." 
works ok and transactions are secure, but the server is also responding to requests through "http://...".  I have 
seen postings describing how to set the response from the WO app to always be "https", which is fine, but I 
would ideally like it if the app ONLY responded to https requests.  

It seems like a bit of a security hole if there is a possibility that a non-secure request can be made (I want to 
have secure data flow both ways, request and response, for stuff like login name and password, etc.).  I  would 
prefer to have the app only respond to secure requests.  

Anyone know how to make that happen (other than by blocking port 80)?  I've tried setting -WOCGIAdaptorURL 
argument to "https://...", but that doesn't do it.

Thanks,
Jay Riopelle.
