Could folks please >briefly let me know where you stand [...] Roy's arguments have convinced me that, if HTTP/1.1 just required user agents to never ignore Cache-Control response headers, this will not lead to a conformance situation where Shell's and my problems are solved. I think it is necessary that HTTP/1.1 allows the `never cache' setting, and other forms of weakening caching restrictions. I think HTTP/1.1 must require clients that weaken caching restrictions to send some warning about this in every request message made while the restrictions are weakened. I'm not convinced that just requiring user agents to warn the user when restrictions are weakened is suffficient. See http://weeble.lut.ac.uk/lists/http-caching/0370.html for an explanation. Two new cache-control request directives, "may-cache" and "min-age" that indicate possible weakening of any "no-cache" and "max-age" restrictions, would work for me. I would not mind having a more elaborate warning mechanism, like the "Cache-Warning" header I defined earlier. Koen.
