In e.g. yesterday's log file, for 950K valid http requests, I find about
with 822K peer status DIRECT/...
Of these, those with squid status some variant of _HIT break down as
follows:
115 TCP_HIT/200
49 TCP_IMS_HIT/304
8 TCP_MEM_HIT/200
12880 TCP_REFRESH_HIT/200
15 TCP_REFRESH_HIT/206
14566 TCP_REFRESH_HIT/304
I understand the REFRESH cases, but what about the first three? Under
what circumstances does a (non-REFRESH) cache hit none-the-less cause a
fetch to an origin server?
Thanks,
