Redirect HTTP to HTTPS

The below code when added to an .htaccess file will automatically redirect any traffic destined for http: to https:

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

For NGINX, the following configuration can be used inside a server block:

if ($scheme != "https") {
    rewrite ^ https://$host$uri permanent;
}
