SSL validation with client (browser) in case of URL redirection

we have a task to redirect a URL say abc.com to on the GTM.

 

Currently we have a cname to point to , since we are using sd.com zone for doing global load balancing. The is pointing to reverse proxys which have the certificate with name "; on them.

 

so if i proceed to create a cname to point abc.com to ( cname ) will it throw certificate errors ? since the cert name is and not nor is it having the initial requestors abc.com. as a san name. I think this will fail certificate validation. Can anyone please confirm on this.

 

If i am correct, i think i should make this redirection to avoid certificate issues.

 

1) point abc.com to instead of directly pointing it to ( and since will redirect to since its related CNAME is already existing ).

 

This way the broswer will be in its request, also include a mention of and thus the certificate name will also match and validation will be successful.

 

Please correct me if am wrong.
