Nginx http to https redirect (maintaining hostname, path and query string - using an HTTP 301)

Nginx http to https redirect

server {
        # Listen on port 80 for any IPv4 address on this server
        # listen docs: http://wiki.nginx.org/HttpCoreModule#listen
        listen 80;

        # Listen on only the selected hostname...
        server_name <HOSTNAME>;
        # ...or use the catchall character if you want to handle multiple hostnames
        # server_name _;

	# Turn off logging for the redirect. Enable this the usual way if you need it: 
	# Access log docss: http://wiki.nginx.org/HttpLogModule
        access_log off;
        # Error log docs: http://wiki.nginx.org/CoreModule#error_log
        error_log off;

	# Rewrite (redirect) the request to https...
	# maintaining the hostname ($server_name), path ($request_uri) and query string ($query_string)...
	# via an HTTP 301 (permanent)
        rewrite ^ https://$server_name$request_uri?$query_string permanent;
}

Note that this gist is incorrect: the $request_uri includes the $query_string (aka arguments), see Nginx Docs.
If you want a something without the $query_string, you have to create it yourself.
