To support more than one SSL virtual host you must have seperate IP addresses for each.

You can get a wildcard certificate to handle multiple virtual hosts on one IP. We got ours from QualitySSL. But we are running Orion on OSX and not Apache.

If this were true than SSL would be broken and the sky would be falling.

I suspect your wildcard certificate permits *.domain.top, not wildcarding *.top.

The issue here is that in order to determine the certificate to decrypt the connection you must first know the virtual HOST in question. Since this is stored in the HTTPS request in the HOST header (which is encrypted) you have a chicken and egg dilemma. You can't tell which certificate to use to decrypt the connection w/o first seeing inside the encrypted payload. So you need to have some unique method of determining which virtual host's certificate you should use to decrypt the connection. Any combination of IP-address:port will work here, but since HTTPS expects a specific port in general operation you're left with needing unique IP addresses. This way you can match the connecting IP address and map that to the right certificate to use.
