I am trying to add range support within my proxy following that scheme: the proxy gets a document, and caches it in a local file. Latter on a request comes in for that document (which is still fresh according to both the request and the cache entry) with a range specification. In that case the proxy will (should/could ?) handle the range request. My concerns are: - Should the proxy emit an 'Accept-Range' header when serving the cached entry (since now that it has entered the cache, the cached resource will handle ranges) - The spec says (13.5.2) that I can implement that only if the Cache-Control directive 'no-transform' has not been set by the origin server, I am not sure I understand the rationale. In particular it seems to me that this case is (potentially) much less "harmfull" than if I were to transform gif images to jpegs - I mean transform the entity - and the client will not be able to distinguish between these two cases since they use the same warning). [that same remark applies to the case where you want to use byte ranges in the proxy (instead of supporting them) ?] I guess I miss something, though, Anselm.
