You can redirect Internet traffic from a particular subdomain to another location. This is usually used when the web pages that made up the subdomain have been moved to another location.
To add subdomain redirection:
Click on the Subdomains button on the home page.
Click on the required subdomain from the first drop-down list.
Click on the Setup Redirection button.
Enter the redirection address in the available field. Make sure that you end the address with a trailing slash (e.g. http://yourdomain.com/).
Click on the Save button.
