 # Running behind NGINX for SSL
 You can (and should) run this tool behind a reverse proxy handling SSL. I recommend nginx with this configuration. Note the *proxy_next_upstream*-directive which tells nginx, that it should only report a timeout as bad gateway, since the backend will respond with certain error codes to ease debugging.
