I don't think I'm confused about what caches do: the concrete example you give is exactly the example I would give. > People who are on the http-caching mailing list may recall a >discussion of whether we should model caches as storing "values" >(of entities + assocatied entity headers) or "responses". I remember the discussion, and I don't think that now is the time to restart it. >In this case, it doesn't really matter which model you follow, [...] Yes, it does not really matter. We seem to be agreeing on what happens in caches, though we all have different explanations (models) of how it happens. What we need now is not some general model, but concrete text. We need text, that exactly defines how caches must behave, for the new 1.1 draft which should be ready on April 1st. Whether this text talks about `responses' or `values' or `entities' as being stored by caches, is an editorial decision that can be made while writing the text. Koen.
