How do you know that those pages were indeed cached? Does the X-Cache-Lookup
header says "HIT"?

If you just modified a "no_cache" option, note that there are other factors
control cachability as well. For example, the origin server (or client) may
send special cache-control directives to prevent caching.

Also note that there are scenarios when Squid needs to contact an origin
server for _cached_ objects. For example, to verify object freshness.

One way would be to play with refresh rules (see squid.conf). Note that what
you want probably violates HTTP, and you will end up serving stale/wrong
pages more often.
