https to https redirect

The best way to think of it is that 1 Cert = 1 IP. While you can use wildcard certs for more flexibility, that doesn't help if you're talking .com and .net.

 

 

With that said, are you simply using A records in DNS? I wonder how this would go if you were to CNAME www.xyz.com to www.xyz.net and have a www.xyz.net cert on your boxes. Might be worth a shot...

 

 

Worst case scenario - you'd need to have Virtual Servers with 2 different IPs, 1 for each Domain. I suspect though that redirecting will trigger a cert warning.
