How Do I Configure a Certificate for a Wildcard Domain?

When you configure a wildcard certificate, the wildcard domain must match the certificate at the same level. For example:

1. If your domain name is a.b.example.com or *.b.example.com, the wildcard certificate must be *.b.example.com rather than *.example.com or *.a.b.example.com.
2. If your domain name is a.example.com or *.example.com, the wildcard certificate must be *.example.com rather than *.b.example.com.

Configuration Method

• To configure a certificate for a domain name:

  In the navigation pane of the CDN console, choose Domains. Click Configure in the row containing the target domain name, click the HTTPS Settings tab, and configure a certificate.
