There are many types of hits. REFRESH_UNMODIFIED, IMS_HIT, etc. most of
these are not separated out from a generic "all hits" statistic.
MEM_HIT is only the hits served from memory which required no
validation or special handling. The label "Disk hits" is a bit
misleading.
NP: if you are actually getting "TCP_HIT" specifically in the
access.log that would indicate there is still a disk cache_dir
somewhere. Or a bug in the label marking, which is not unsurprising
since the labeling system is a bit old/fragile.
