You have not provided enough information for us to know whether this is
a problem or testing mistake.

What is this unstated "minimal change" you made that made caching
suddenly stop working?

What exactly does "visiting the same website over and over again" mean?
what exact actions did you do?
  - Pressing refresh, Shift+reload, or CTL+refresh in a browser will
*force* a MISS - yet comes under the description you gave.
  - some tools send headers to forbid cached contents being delivered by
default. So cannot be used for this kind of test without special options.

The more specific details you can give, the better anyone help can be.

Please do not do that "allow all".

For one thing it makes your NOC ACL pointless, *everybody* is allowed to
use your proxy for whatever they want to do.

If you did it to debug a caching problem, be aware that http_access has
nothing to do with cache.
