I have just moved my websites to a HostGator Baby account and the first thing that I do for Addon domains is to redirect subdomains to each domain in order to avoid duplicated content problems.

This is the .htaccess template for Addon domains:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^addondomain.maindomain.com$ [NC]
RewriteRule ^(.*)$ http://www.addondomain.com/$1 [R=301,L]
RewriteCond %{HTTP_HOST} ^addondomain\.com$ [NC]
RewriteRule ^(.*)$ http://www.addondomain.com/$1 [R=301,L]

This way, both addondomain.maindomain.com and addondomain.com redirect to http://www.addondomain.com.
