Abstract
A method is provided in one example embodiment and includes receiving a message from a client destined for a server; embedding in the received message an X-Forwarded Source (“XFS”) value identifying the client; and forwarding the received message comprising the embedded XFS value to the server. In one embodiment, the message is an acknowledge (“ACK”) message of a Transmission Control Protocol (“TCP”) three-way handshake. The XFS value may include at least one of a source IP address of the client and a source port designator associated with the client. The received message may be sent in response to a Transmission Control Protocol (“TCP”) Synchronize-Acknowledge (“SYN-ACK”) message received by the client from the server. Additionally, the XFS value may be embedded in a Transmission Control Protocol (“TCP”) header of the message.
