What is Multi-domain SSL?
Multi-Domain, also referred to commonly as SAN Certificates, utilize Subject Alternative Names (SANs) to secure up to 100 different domain names, subdomains, and public IP addresses, using only one SSL Certificate and requiring only one IP to host the certificate.
What is a2ensite?

What is a Multi-domain SSL certificate?

This type is also commonly referred to as a UCC SSL (Unified Communications Certificate) or a SAN SSL (Subject Alternative Names).
Can I have more than one SSL certificate on one virtualhost?
You can only have one certificate per virtualhost. But this is free software. There is no cost (and very little overhead) to just adding a separate virtualhost for each domain with its own certificate.
How much does it cost to add multiple domains to virtualhost?
There is no cost (and very little overhead) to just adding a separate virtualhost for each domain with its own certificate. Unless the content ever differs, I would go one step further and pick one domains as your main domain and have all the others redirect to it.

here are the two 443 virtual hosts. I’ve tried referencing the virtual hosts as you see below, as well as other variations such as simply ” and ”. I also played with the NameVirtualHost references, but still to no avail.
How does Apache work with SSL?
Apache uses the host header and matches it to a name-based virtual host, and serves whatever is there. Browser negotiates SSL encryption with server. The name of the site (www.example.com) is specified in the certificate, so at this stage it has to match the SSL or else the browser throws a warning that something is wrong with the SSL connection.
