Hi all,

In fact, I was looking for a transparent redirect. Here is what I finaly did :

server {
server_name ~^(?<lang>.+)\.example\.com$;
location / {
rewrite /(.*)$ /$lang/$1 break;
proxy_pass http://www.example.com;
proxy_redirect http://www.example.com http://$lang.example.com/$request_uri;
}
}

server {
listen 80;
server_name www.example.com;
...
}

One more question though : is there a way for Nginx to rewrite all the URLs in the generated page so they are all SEF ? ie: http://fr.example.com instead of http://www.example.com/fr ?
