Comment:

* Section 4.1.4 "Proxies should follow standard HTTP procedures in
respect to caching..." This seems a strange way to phrase it, and I
don't think it's useful to use RF2616 language here.

WG Notes: See: http://www.w3.org/2008/10/20-bpwg-minutes.html#item03 Final resolution: - Ref LC-2070, resolve yes, and change para 1 to say "Aside from the usual caching procedures defined in RFC 2616, in some circumstances ..."

Resolution: We agreed and have reworded the section to remove the weird use of normative terms to refer to RFC2616. The updated text is available at: http://www.w3.org/TR/2009/WD-ct-guidelines-20091006/Overview.html#sec-serving-cached-responses
