Support SSL SNI
Please add SNI support for SSL certificates. It's been supported by all browsers for quite a while and will enable multiple SSL certificates for different domains on a single IP address. http://en.wikipedia.org/wiki/Server_Name_Indication
Apache supports this, e.g. https://www.digitalocean.com/community/articles/how-to-set-up-multiple-ssl-certificates-on-one-ip-with-apache-on-ubuntu-12-04
