        location /_x_accel_redirect/ {
            internal;
            alias /;
            # Add upstream response headers that would otherwise be omitted
            add_header Access-Control-Allow-Origin $upstream_http_access_control_allow_origin;
            add_header Access-Control-Allow-Methods $upstream_http_access_control_allow_methods;
        }
