For those interested in using SSL certificates, I would like to bring up two very important things to keep in mind:
- Under most circumstances, each site that utilizes a SSL certificate must have a unique, static IP address
- All SSL certificates are not the same so be sure you understand what type of certificate you are purchasing
Before purchasing or beginning to architect your domain supporting SSL, I encourage you to read and fully understand how SSL works. In order to support valid SSL authentication on all operating systems and web browsers, each domain that utilizes a SSL certificate must have a unique, static IP address assigned to it. In addition, the web server application used must be configured at a minimum to use IP-based virtual hosts.
