Two SSL Certificates on one domain?

Hi,

I have a SSL Cert on my CP at http://cp.myhost.com . I am adding various shopping carts to my account website for demo purposes. I want to use an SSL cert during the demo logins. My current cert doesn’t cover http://myhost.com/demos without producing a warning message that the cert is not exactly for the domain. Can another cert be installed at http://myhost.com to cover the demo sites?

Thanks!

Yes, you can always have as many SSL certs as required, as long as they have different Common Name(CN). Here if you have cp.domain.com, you can also have seperate cert for domain.com.
Or even for sub.domain.com, www.sub.domain.com , and so on.
Just switch domain.com to dedicated IP:

and generate a CSR/private key:

Next get your signed cert for domain.com as you did for cp.domain.com
