You add a domain alias to your website intending it to add the host headers in IIS to a DNN portal in your installation. Instead, when you visit the alias, you are re-directed to the original domain.
Plesk 12 has a Redirect with the HTTP 301 code check box enabled by default.
- Log into your Plesk Control Panel.
- Click on Subscriptions
- For the domain that has the associated alias click Manage (or Open) in Control Panel.
- For the alias in question uncheck the Redirect with the HTTP 301 code check box.
- Alternately, when creating the alias initially, remove the check from the box.
