Managing Shared SSL
SSL stands for “Secure Socket Layer” and you can use this feature to protect all data exchanged between your Web site and the client. Shared SSL is a means of secure Web server access without requiring users to purchase a digital key.
In this case, only one domain should have real SSL sertificate. We will call it Master SSL Domain. Other domains, which are set up to use Shared SSL will use its resources.
To choose the Master SSL Domain from the list of domains which have SSL support enabled, go to the Server > Shared SSL page. In order to do this, set the Enable shared SSL checkbox and choose, which domain you want to be the Master SSL Domain.
