That is not an accurate description of current HTTP/1.1 traffic nor of
Squid behaviour.

The separation of static vs dynamic is irrelevant for the purposes of
caching and *does not* impact on the MISS situation.

REFRESH is a sign of the content being either dynamic, private or stale.
HIT is seen on both static and dynamic types of object. Neither is a
sign of being static and MISS can occur for many reasons unrelated to
data being either static or dynamic.

The only difference between them is that dynamic is HIT for shorter
times and REFRESH happens more often, compared with longer HIT period on
static content.
