Is the 200's ACK MUST be proxied to UAS? Can a proxy send ACK to UAS when received 200 response, and omit the following ACK from UAC.      ACK for 200 OK is end to end and hence a proxy cannot send ACK to UA on receiving 200. Also, ACK for 200 OK will arrive at a proxy only if it had record-routed.   Thanks Kowsalya
