Assume we are using relative TCP sequence and acknowledgment numbers. This is a sample three-way handshake and an HTTP request which is successfully returned (Code 200). There are variables X, Y, and Z, replace the variables with the correct values for SEQ, ACK, and LEN:

Client Client TCP SYN SEQ 1 ACK 0 LEN 0 TCP SYN ACK SEQ 1 ACK 1 LEN 0 TCP ACK SEQ X ACKY LEN Z HTTP 200 GET ACK X SEQ Y LEN 343 TCP ACK SEQ X ACKY LEN O HTTP/1.1 200 OK SEQ X ACK Y LEN 853 TCP ACK SEQ X ACKY LEN O Server Server
