How do I set up a domain Alias with Plesk?

1. Log in to the Plesk control panel.

2. Click Add New Domain Alias in the Websites & Domains tab:
3. Enter the alias domain (secondary mapped domain).

4. Make sure "Web service" is enabled, and "Redirect..." is disabled.

5. The original website domain content should now appear when visiting the Alias, but it might take up to 24 hours to see the update.
