How to configure diff https certificates for each subdomain?

[HasibullahMahmood]

I have a domain let's say example.com and a subdomain web.example.com and also I have two certificates for both of them. How can I send certificates based on the subdomains?

Is better to use Wildcard SSL Certificate
