Hi all, I suggest one or more additional response codes to take into consideration for the following situations: In the case when a proxy want to offer a different/no proxy to use instead. (Now can return 403 forbidden only.) [explanation] There are good reasons to make possible a such offer: when a proxy server moves, when [the admin of] the proxy knows a better choice for a given origin server or for a given user, when a proxy to proxy (routing like) protocoll will be available, and a better choice is learned from that protocoll, when a caching proxy want to offer bypass, because knows that the response isn't cacheable (by cacheing only the Cache-Control directive from a previously forwarded request). Some additional reponse headers can be used to differentiate between different reasons and the Location: (and URI: for additional alternetives) can be used to carry the URL of the recommended proxies. Sometimes even origin servers may use this feature when a very distant client makes a direct request. This new response code(s) improves the protocol because it makes possible new features, resulting better scaleablility of the Web. Andrew.
