If the client sends an ACK + PSH package represents the confirm receipt, and push the request to the server, right???????
Then the server after receiving the message back to the first a ACK confirmation, then reply to the request, because the MSS restricted, will block to send, so at the time of piecewise send an ACK, and an ACK + PSH is what mean? ACK + PSH represents a package has been sent and send to empty the cache??????? And an ACK is confirmed, why the reply message will send ACK???
O, for help,
