I suggest to use $scheme like in:

rewrite ^(.*) $scheme://www.example.org/$1 permanent;

to keep the https connection (if a client wants to use it). otherwise your
server drops the https connection and the client will connect over http.
i.e.: if you want to use /wp-admin only over https with
"define('FORCE_SSL_ADMIN', true);" in /wp-config.php, it will safe you a
lot of annoying behavior...
