Yes, that's a MUST level requirement in 14.20 Expect.. third paragraph, and further clarified with another MUST level requiement in the fifth paragraph.. But older versions of HTTP/1.1 did not specify Expect and implementations based on those versions will just pass it thru as any other extension header, but I somehow doubt the proxy vendors are stuck at that..
