RE-VERSION: I had written a long message outlining my reasons for raising the RE-VERSION issue, but after writing it, and with the help of John Klensin, Ive realized that the real issue here isnt the response version exactly. The problem I have is that in the spec, 1.1 proxy behaviour when talking to a 1.0 client and 1.1 server is underspecified. It isnt clear how a proxy should act in generating response versions, from cached or origin responses, how it should determine cache applicability, and still make best advantage of 1.1 features, in a mixed version situation. If we require that 1.1 proxies always upgrade requests to their highest version, then this issue will go away. (at least from me ) If this is required, then the proxy will have all the information it needs to determine how to act, and it will be the proxy's responsibility to downgrade the response to a lower version client.Received on Sunday, 10 August 1997 18:51:41 UTC
