CodePudding user response:

Not, depends on the type, if it is a certificate of matches, will all wildcard subdomains of aaaa.com, if not, can only buy, according to the number of domain names in the background to submit to binding domain, and then charge by the number of binding domain,
In addition, the aaaa.com domain name certificate, generally the default help you additional binding www.aaaa.com, this will support all kinds of certificate,

CodePudding user response:

I think not,
You SAN contain B server domain name in the certificate?
If not, the visit will surely quote certificate error,
