In Nginx, how can I rewrite all http requests to https while maintaining sub-domain?

Question

I want to rewrite all http requests on my web server to be https requests, I started with the following:

server {
    listen      80;

    location / {
      rewrite     ^(.*)   https://mysite.com$1 permanent;
    }
...

One Problem is that this strips away any subdomain information (e.g., node1.mysite.com/folder), how could I rewrite the above to reroute everything to https and maintain the sub-domain?

I have been using nginx 0.8.39 and above, and used the following:

 server {
       listen 80;
       rewrite ^(.*) https://$host$1 permanent;
 }

Sends a permanent redirect to the client.

The mothod you guys are using is actually one of the nginx pitfalls:

The correct code would be:

server {
       listen         80;
       server_name    my.domain.com;
       rewrite        ^ https://$server_name$request_uri? permanent;
}

server {
       listen         443;
       server_name    my.domain.com;

       ssl            on;

       [....]
}

I know it is a small change, but I thought it was useful to add.
