Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have two domains for a website (we're using Apache), and The website responds to a wildcard subdomain for both of these. I want, however, to have the .com as the canonical domain. By that, I mean, I want to redirect (301) everything to the .com, but maintain the subdomain. For example. => =>

I don't know enough about regular expressions to work out how to set this up. Can anyone point me in the right direction?

Try this:

<VirtualHost *:80>
    ServerAlias *
    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^(.*\.)example\.org$
    RewriteRule ^/(.*)$$1 [R=301,L]

..then have your other vhost (the one serving the content for configured with ServerName and ServerAlias *

Thanks a lot, this worked perfectly. Even better, I think I understand how it works, too. I hate just copying and pasting stuff without actually comprehending what it's doing. – Edd Morgan Aug 23 '12 at 13:15
@EddMorgan Great! Let me know if you'd like to see more explanation for the individual components of the config; this answer is kinda short on explanation by my standards, heh. – Shane Madden Aug 23 '12 at 17:02
