If you want to add a secondary domain (domainB.com) that mirrors your primary domain (domainA.com), follow these steps:
- Point the secondary domain (domainB.com) to the same IP address as the primary domain (domainA.com)
- Add the secondary domain (domainB.com) in the Domains section. You don't need to set it as primary.
After completing these steps, automatic redirection from the secondary to the primary domain will take effect.
