Nginx: Send all 80 to 443

nginx80-443

# /etc/nginx/sites-available/production  <-- in same VirtualHost container as the 443 one, above it 
server {
    listen    80;
    server_name    sample.com www.sample.com;
    rewrite ^(.*) https://sample.com$1 permanent;
}

As stated in http://nginx.org/en/docs/http/converting_rewrite_rules.html it is ineffective to use rewrite when no actual rewriting is done.

server {
listen 80;
server_name sample.com www.sample.com;
return 301 https://sample.com$request_uri;
}

Just adding this information here if someone comes across it in search for information on how to do it. :)
