Picking this issue back up and CC:ing Jeff for his recollections (see <http://trac.tools.ietf.org/wg/httpbis/trac/ticket/174> for background). Sorry, I don't have any clear recollections. I did find some relevant emails that I had sent: (email 1) (Thu, 02 Jan 97 10:55:03 PST) in private (not to the mailing list) that contains these paragraphs: The current issues in the HTTP WG related to caching, for HTTP/1.1 in particular, are limited to a few issues that seem particularly pressing: (1) there is an apparent bug (or at least a "poor design choice") in the current draft re: the "proxy-revalidate" Cache-control directive, probably my fault. We will likely end up defining a new directive to avoid the problem, and I've volunteered to write up a brief draft on this. (2) Several related documents will need to be revised to deal with this bug. (email 2) (Mon, 21 Apr 97 19:19:18 PST) to Larry Masinter and Jim Gettys (also not to the entire list): I thought the http-versions draft was ready, but looking at ftp://ietf.org/internet-drafts/draft-mogul-http-revalidate-00.txt I see that contains two alternatives, and clearly cannot progress until we've reached consensus on which one. You didn't read it carefully enough. Section 3 lays outs a number of alternatives, to show that they were considered, and includes an analysis to show what their benefits and drawbacks are ... but does not propose any of these directly. Section 4 precisely defined a specific proposed change. This is the "normative" part of the proposal, i.e., a set of edits to be applied to RFC2068. If Jim finds anything in section 4 ambiguous, then I need to fix this; otherwise, not. Were you intending to release a new draft so I can 'last call' it? The only glitch is that Roy, during a hallway chat at the WWW6 conference, casually suggested that he wanted me to replace the term "proxy [cache]" with "shared cache". He hasn't ever sent email to this effect, but I have no objections to making this change. I consider it to be an editorial issue (clarification) and it seems pointless to spin another I-D version just to clarify a single word. I don't remember what Jim did as a result of this exchange. (See http://tools.ietf.org/html/draft-mogul-http-revalidate-00 for the draft mentioned above.) Also, Duane sent an email on 19 Jul 2000 to the http-wg list Subject: Questions (errata?) about caching authenticated responses which brings up some questions about proxy-revalidate; see <http://ftp.ics.uci.edu/pub/ietf/http/hypermail/2000/0142.html> That's all I can remember at this point, but I think a careful reading of http://tools.ietf.org/html/draft-mogul-http-revalidate-00 might clarify much of the history. -Jeff
