Claim Text:
1. A computer-implemented method for adapting legacy control messaging in a Point-of-Presence (PoP) comprising a director distributing packets across a plurality of servers, wherein the director comprises a processor, the computer-implemented method comprising: receiving at the director, a control message that is directed to a particular server of the plurality of servers having an established session with a client, the control message comprising a first header specifying first addressing of the control message and a second header specifying second addressing of an earlier packet transmitted by the particular server; comparing, by operation of the processor, the first addressing and the second addressing; rewriting, by operation of the processor, the first header with the second addressing from the second header when the first addressing and the second addressing are mismatched; and passing the control message from the director to the particular server when the first addressing and the second addressing are matched, wherein said passing comprises identifying the established session to which the control message relates by hashing at least the addressing from the control message first header and forwarding the control message to the particular server.
