ATS 10.0.x, `*_HIT` always on event log. NO `TCP_MISS` with ttl-in-cache on cache.config at all

hello !

i would like to ask about cache.config

cache.config is below

----------------------------------------------------------------------------------------------------------------------

`dest_domain=test2222.kinxzone.com ttl-in-cache=20s`

----------------------------------------------------------------------------------------------------------------------

records.yaml is below

----------------------------------------------------------------------------------------------------------------------

```

```

and i did `curl https://test2222.kinxzone.com/cat/cat1.jpg`

about 20 seconds later, i did `curl https://test2222.kinxzone.com/cat/cat1.jpg` again

but always `*_HIT` Nothing `TCP_MISS`

even i set revalidate 20s
and, pin-in-cache 20s

but same result

i refered https://docs.trafficserver.apache.org/en/10.0.x/admin-guide/files/cache.config.en.html

i know that PURGE method can be used to clear cache exactly

curl -X PURGE https://test2222.kinxzone.com/cat/cat1.jpg

it works well,

and invalidating cache by using regex revalidate plugin as well

event.log is below
