Q:

Can I use 2 separate SSL certificates for 1 domain name?

I've noticed it is a lot cheaper to buy a single website SSL certificate than a wildcard certificate.
My question is if I have 2 applications setup in IIS:
1. website.com
2. subdomain.website.com
Firstly, would I be able to buy 2 individual certificates for the website.com and subdomain.website.com?
Secondly, assuming I was able to buy the above certs, would it actually work?
Many thanks!

A:

Yes you can. The domain name is recorded in CN field (single domain or a wildcard). There is also SAN extension that allows you to use the same certificate on different domains (sub.domain.com and domain.com are considered two different domains).
