Hi,
Therefore, in order to support both HTTP/1.0 and 1.1, we only need to use
"Pragma: no-cache", right? since proxy which supports 1.1 also regonizes it

Or, we still need to add "Cache-Control: no-cache"?

ps: right now I use both, maybe I can eliminate "Cache-Control: no-cache",
any risk? any differences?

thanks a lot
