[dancer-users] playing with path_info before matching routes

[Matt Mallard]

One possibility is to use wildcard path matching and splat or named 
parameters in route paths - the upside, it doesn't call hook again, the 
downside, it matches anything not just your language codes.  You could 
prefix it though with even a single letter like 'l' to just narrow it 
down to those pages:

www.exemple.com/l/en/some_page
www.exemple.com/l/de/some_page

get '/l/*/*' => sub {
	my  ($lang,  $page)  =  splat;

	template ("$lang/$page");
};

It's a bit ugly though...

Matt
