How to start https service only?

[Hongwei Li]

Hi,

I have a fc3 system that works well.  My question is how to make the
system's web service available only to https, but not to regular http? 
i.e. people can browse this system only using https://my-server, but not
http://my-server?  I tried to not open port 80, but only port 443 in
iptables, but it seems no effect, http://my-server is still working.

Thanks for any help!
