Yes, DON'T run Squid as a transparent proxy and your users will do
this automatically for you.

The problem with running Squid as a transparent proxy is that then the
browsers do not know there is a proxy cache, and does not indicate
the user wants a fresh copy when the user uses the reload button.
When the browser is configured to use a proxy everything just works..

There is a few tweaks you can enable in squid.conf to minimize the
downsides in content freshness of transparent interception caching

  - ie_refresh on
  - refresh_pattern with a limited max age
