Summary: This draft specification defines HTTP caches and header fields for
controlling the cache behavior.

Major issues:

Minor issues:
- In the HTML version of the draft, the reference to [Semantics] does not work
properly. I looked at the xml source which looks fine. I suspect it is
something to do with the tooling.

- It is not clear to me which draft is creating the "Hypertext Transfer
Protocol (HTTP) Field Name Registry". It seems both this draft and
draft-ietf-httpbis-semantics are creating it? Perhaps you could remove the text
in this draft saying "introduce the new" and just ask IANA to update the
registry with fields in Table 1 of this draft.

Nits/editorial comments:

- Section 1: When does a client or server act as "tunnel"? I don't know if it
is absolutely necessary to explain the term. You can decide.

- Section 1: HTTP caching's goal is significantly improving performance -> HTTP
caching's goal is to significantly improve performance?

- Section 1.3: Maybe it is obvious to many readers, but I was not sure what is
meant by a "canned string"?

- Section 3 vs Section 4: "A cache MUST NOT store a response to a request
unless:" does not have a comma before unless while "When presented with a
request, a cache MUST NOT reuse a stored response, unless:" has a comma before

- Some of the bullets in section 3 and 4 were hard to parse. Take for example:
"When presented with a request, a cache MUST NOT reuse a stored response,
unless: the stored response does not contain the no-cache cache directive
(Section, unless it is successfully validated (Section 4.3), and". I
am not sure how to simplify the text on all these requirements.
