Route rewriting length

[eluser]InsiteFX[/eluser]
Note: Routes will run in the order they are defined. Higher routes will always take precedence over lower ones.

Code:

$route['default_controller'] = 'welcome';
$route['404_override'] = '';

$route['admin/([a-z]+)'] = 'admin/area/$1';
$route['admin'] = 'admin';
