But anyway, if someone is trying to access to an SSL url (HTTPs), he might need to accept the certificate first (if you are using openSSL) and then after that, the user will be redirected to an HTTP url.
I might be wrong, but i don't believe you are able to redirect an user without accepting the certificate since you are using port 443 and not port 80 so the browser is already expecting a protocol with and SSL key in it.
