It is possible that the server has problem sending data packets to the client. I have no idea why because connection initialization packets are transmitted without delay. To help you withthe sniffer: A TCP session is established with a 3 control packets (without mention ARP packets to resolve IP/MAC addresses): Client send SYN Server respond with SYN-ACK client respond with ACK then data and ack packets are sent/received by either party. -- Contribute to the SSL Effort.
