The trick we do here is to make one virtualhost for the “main” domain you wish indexed (and shown in browsers etc) and another one for all the other domains that will simply redirect to the main domain.
<VirtualHost *:80> ServerName example.com ServerAlias example.net ServerAlias example.biz RedirectMatch permanent /(.*) http://www.example.com/$1 </VirtualHost> <VirtualHost *:80> ServerName www.example.com ... other stuffs ... </VirtualHost> |
