I’m using squid 3.5.2
and I’m browsing the same website many times but no “HIT” in logs !!!
already enabled https and cert imported .
plz help me why i don’t see HITs in my access.log ?
there are some sites I’m very interested with like ==> https://www.ruzivodigitallearning.co.zw.com <https://www.ruzivodigitallearning.co.zw.com/>
plz have a look on my config below and advise me with best options to optimise caching and hit ratio increase
cheers
