Would be useful, at least for accelerator > setups... Log when an URI goes from Vary to non-Vary during normal requests should be fairly easy. Just a debug statement in the right code path.. It's harder to log when the server behaves bad wrt ETag, doing so would require interpreting Accept-Encoding and Content-Encoding and detect when the server responds with Vary: Accept-Encoding and an ETag matching an object with incompatible encoding. But both these really belong in tools such as the cacheability engine.. Regards Henrik
