Hi Jean-Philippe and all,
I know that this thread is almost 6 moths old, but I think the redirect option is becoming critical and needs to addressed soon since google and firefox will now penalize sites that don't have secure sites. The issue is, many people will just type URL without https, and they will get "forbidden" message which will make them think that the site is down. But they just need to be redirected to https site when "Force Secure Connection" option is enabled, just like it is done now with server-manager and webmail.
