This makes them primarily the > responsibility of the negotiation subgroup. THe only problem with your position is that desigining negotiation while igoring proxy/caching issues can't be successful. Either negotiation won't work in the general cases or proxies will never be able to determine if a response can be delivered in response to another requrest. Furthermore, to some degree or another all clients provide caching as well so caching is not simply a proxy issue. I think Larry Masinter's split makes much sense, especially considering the broad participation in the proxy/caching sub-group. If the negotiation group can identify how to specify and what to negotiate then the join the caching/proxy discussion to make sure we end up with a cohesive mechanism which covers all issues.
