A method of identifying the originator of a message transmitted between a client and a server system is provided. The method includes modifying a message to be transmitted between a client and a server system to include a session identification flag and/or a session identifier(e.g., at an end of the message). The method optionally includes one or more of the steps of re-computing a control portion of the message to reflect the inclusion of the session identification flag and the session identifier, transmitting the message between the client and the server system, and checking the transmitted message for the session identification flag, reading the session identifier of the transmitted message to determine the originator of the message, removing the session identification flag and/or the session identifier from the transmitted message, and re-computing the control portion of the message to reflect the removal of the session identification flag and/or the session identifier
