Hi, AFIAK, The 503 error is when our connection request is in the server's backlog, but unfortunately, server cannot accept, server will send FIN, ACK or RST, so our connection is shutdown The 408 error is when the server 's backlog is full, and we receive nothing from the server until timeout period expires Do I understand correctly, please explain more about this -- Khoa Pham HCMC University of Science Faculty of Information Technology -------------- next part -------------- An HTML attachment was scrubbed...
