This question already has an answer here:
Is it possible to use more than one certificate on the same sever at the same time, on the same connection? If I have a certificate from Alice Keys CA and another from Bob Security CA, is it possible to serve both, for the benefit of those browsers that trust only AliceCA and those which trust only BobCA?
This is not the same as "Certificate verified using two different paths" question, because I'm referring to two completely different certificates:
- ACA root certificate self-signed -> My A certificate for mysite.org
- BCA root certificate self-signed -> My B certificate for mysite.org
