Fix for SSL redirect if ssl port != 443
Before it used to forward to https://site:80 as it only checked for
domain[port] to be !=443, wich the redirecting vhost usualy is.
Now we check for destination port !=443.
Customer still has to be carefull when setting ports and IPs,
different ports on different IPs on same domain will always cause
trouble.
