Re: Minor fixes to draft 05

	I hope these are self-explanatory -- they are all minor and mostly
	due to revision errors.  Since we need a new draft anyway ...

I have problems with a couple of these, since they appear to change
the specification in ways that either might be inadvertent on your
part, or haven't been discussed sufficiently.

    *** 3786,3793 **** [13.1.1 Cache Correctness, leftover from prior change]
	   origin server is violated (see section 13.1.5 and 14.45).
	4.       It is an appropriate 304 (Not Modified), 305 (Proxy Redirect), or
	   error (4xx or 5xx) response message.
    - and it is the most up-to-date response appropriate to the request the
    - cache has (see section 13.2.5, 13.2.6, and 13.12).
      
      If the cache can not communicate with the origin server, then a correct
      cache SHOULD respond as above if the response can be correctly served

I'm not sure why you propose deleting those lines.

    *** 4022,4029 **** [13.2.3 Age Calculations, as requested by Ben Laurie]
      age of a response or cache entry.
      
      In this discussion, we use the term "now" to mean "the current value of
    ! the clock at the host performing the calculation." All HTTP
    ! implementations, but especially origin servers and caches, should use
      NTP [28] or some similar protocol to synchronize their clocks to a
      globally accurate time standard.

      age of a response or cache entry.
      
      In this discussion, we use the term "now" to mean "the current value of
    ! the clock at the host performing the calculation." Internet hosts that
    ! use HTTP, particularly those hosting origin servers and caches, should use
      NTP [28] or some similar protocol to synchronize their clocks to a
      globally accurate time standard.
      
If I understand your use of the word "Internet" (as a replacement for
the word "all"), this change now means that intranet hosts (i.e., those
not directly reachable from the Internet) are not expected to
have synchronized clocks.

I have no idea why anyone would want to run an intranet Web any
differently than the Internet Web.  But in any case, this is a
"should", not a MUST, and so I see no reason to change the suggestion
from the draft-05 version.

Minor nit: shouldn't this be "an MD5 digest" rather than "a MD5 digest"?
