First of all, you must identify what is the default vhost for port 443 in your server (the first SSL vhost loaded by Apache) and edit it's configuration file. Most users have an ssl.conf file in their servers, with a vhost for port 443 configured there. As the name of this file begins with "s", it will load before the vhosts configured in vhosts.conf (which begins with "v"). So, check if this is your case (the answer is "yes" for virtually everyone) and change the protocols in that file. That's enough!
