I think there's a problem. If both If-Non-Match and If-Mod-Since are given, and they are evaluated to TRUE and FALSE respectively, the algorithm yields 304 Not Modified. The "Not Modified" response is totally wrong, since the ETag has been updated. For example, if the current representation has ETag=v1.0, Last-Mod=7/1, and the request has If-Non-Match: v1.1 If-Mod-Since: 7/4 the server should respond 200 with the current representation, not a 304. The solution seems to be that, if both headers are given, only If-Non-Match should be looked at; the If-Mod-Since condition must be ignored. Zhong Yu
