SSL
 

Thank you guys for your great job!

It is not a big deal to enable SSL on every domain with shared ip on the same 443 port. I have seen this implemented on Plesk, and cPanel. Please note that it is messy to use many different ports or ip's if you want to host hundreds of domains. On the other hand, customers would certainly not like to use custom ports instead of default port.

You can create a lot of SSL sites on one IP on 443 port.
40xx is only recommended port but you can change it to any value and to 443 of course.

But you should know: Apache will always give SSL certificate from first site (on this IP on 443 port) for all such sites.
