My first solution was to put Apaches’s directive ServerAlias in the site’s virtual host configuration. This lead to content duplication since domain.com and domain.net and www.domain.com are two different web sites for the rest of the world. To avoid this problem the only solution I’ve found was to create two different virtual hosts and set Apache’s Redirect directive. The first VirtualHost will hold all the domains aliases and redirect permanently (301) to the “main domain”

<VirtualHost ip_address:80>
    ServerName domain.com
    ServerAlias domain.net
    ServerAlias domain.biz
    RedirectMatch permanent /(.*) http://www.domain.com/$1
</VirtualHost>
 
<VirtualHost ip_address:80>
    ServerName www.domain.com
    etc...
</VirtualHost>
