The Resiliency of HCL Domino and how to get Multiple SSL Certs to work with it

There was a technical limitation since removed in Domino 11 related to how Domino handled the SNI(Server Name Indication). Prior to R11 you can only use one SSL certificate per IP address in Domino. Since I run about a dozen domains on my server, this was not helpful, but now, it works quite well.
