HTTP includes the option of replying to a If-Modified with 304 for
Not-Modified or 200 for Modified.

I think Squid should have been logging them as 304/REFRESH_HIT and
200/REFRESH_MISS though. This needs a closer examination.

And brings some in for me as well. I followed the Cachemgr and SNMP
variables in the code to produce that first answer.

I'm not sure at this point why you get 0.0000 for the not-modified which
I would expect to be non-zero from those 304 replies.
