The only change i have made is adding NOC ACL and uncommenting the
cache_dir ufs.
What exactly does "visiting the same website over and over again" mean?

I expected when i visit a website for the time it will miss and after
retrieving it that squid will cache it internally. if i visit the same
website again, squid to read it from the local cache. i was visiting by
adding a new tap using chrome or visiting from another browser like MS edge
or IE.
Please do not do that "allow all".

Thank you amos, I have changed to http_access deny all instead of
http_access allow all
Please ask me anything else i should share with so that you can help me.
thank you.
