routes problem ? (thx for reading)

[eluser]starenka[/eluser]
Hi,

trying to implements easy multilang site with uris as:

/cs/user/join (or just /user/join)
/sk/user/join
etc etc..

so i added a route:

Code:

$route['(cs|sk|pl)/(.*)'] = "$2/$1";

but when i try to get the language segment in controller...

Code:

class User extends Controller
{
    
     function join($language)
     {
         var_dump($language);
     }    
}

i allways get "the method" segment...

any clues? or more elegant solutions?
