nginx_force_www []

This is an old revision of the document!

The right way is to define a separated server for the naked domain and redirect it.

        
              server {
    listen 80;
    server_name example.org;
    return 301 $scheme://www.example.org$request_uri;
}
 
server {
    listen 80;
    server_name www.example.org;
    ...
}

Note that this also works with HTTPS site.
