I propose a simpler rule: > You may use "HTTP/1.1" as your protocol version only if you are > willing to guarantee that all HTTP/1.1 headers used will mean what > HTTP/1.1 says they mean, and all HTTP/1.1 directives will be > followed. In practice, this will mean that simple 1.1 proxies that don't want to rewrite headers will use the "minimum" algorithm: if the client is 1.0, they'll pass on 1.0. More complex proxies might want to upgrade even 1.0 clients to 1.1 protocol on the way out, but at an additional cost, e.g., to upgrade a 1.0 client to a 1.1 call to a 1.1 origin server, a proxy might have to introduce "cache-busting" techniques to guarantee that 1.1 cache directives are followed, or deal directly with 301 or 302 results from a POST, etc.
