It seems like what you want is some kind of globally unique ETag, e.g., such that a cache could presume that if it had data with same globally unique ETag anywhere in its cache, it could use that data; on the other hand, you also want those etags to be 'global' Since there are both 'strong' and 'weak' etags, maybe we could add global etags too. For the most part, you can just use them like (strong) etags, but the origin server guarantees global uniqueness. "Differential-ID" is a like range retrieval and has many of the same caveats. The header name should reflect that it is a modifier to the request rather than (just) an identifier. Larry
