NGINX Reverse Proxy for Web UI

If you're using NGINX as a reverse proxy for Web UI, as of version 4.0.3, assuming your reverse proxy is local, your location /qbt/ should have the following settings:

location /qbt/ {
    proxy_pass              http://127.0.0.1:8080/;
    proxy_set_header        X-Forwarded-Host        $server_name:$server_port;
    proxy_hide_header       Referer;
    proxy_hide_header       Origin;
    proxy_set_header        Referer                 '';
    proxy_set_header        Origin                  '';
    add_header              X-Frame-Options         "SAMEORIGIN"; # see note
}

Note: For some users, several windows in the Web UI will still be blank, such as when adding a new torrent from a URL/magnet or local file. If so, try adding the following line to the location block:

add_header X-Frame-Options "SAMEORIGIN";
