    map $http_x_request_id $reqid {
        default $http_x_request_id;
        "" $request_id;

    server {

        # -------------------------------------------------------------------------------
        # If you don't trust client and front nginx's header, or you are sure this 
        # is the first front nginx, just set the variable $reqid to a new random value.
        # Use `map block` above, or use `set line` below, but don't use both.
        # Uncomment the `set line` below to `set new random value`.
        # -------------------------------------------------------------------------------
        # set $reqid $request_id;
