CodeIgniter's Subdomain Support

[eluser]Colin Williams[/eluser]
For starters, I never include a domain in my base_url setting. I don't know why anyone would.

Code:

$config['base_url'] = '/';

And for database configuration, I like to name the database groups by either the server IP or hostname. Then you can set $active_group to something like $_SERVER['SERVER_ADDR'] or $_SERVER['HOSTNAME'], so it's dynamic in that way.
