| You may also see gateway ip/proxy ip with some null requests. This is normal. After one request is served, the IP will be reset to the LB IP before a new request arrives. When a new request arrives with the "x-Forwarded-For" header, it will be updated. For keep-alive connections, in between two requests, the LB IP will shown on the real time request list. | You may also see gateway ip/proxy ip with some null requests. This is normal.
