In order to redirect the domain myotherdomain.com to a CMS page, you need to
- Enable Web Site Forwarding at your Domain Registrar. (Some registrars like GoDaddy offer this for free)
- Once Web Site Forwarding is enabled, you can redirect the domain of myotherdomain.com to http://www.myregulardomain.com/nameofpage through your Domain Registrar.
You are done!
