It works both ways.

allowed content are allowed to be cached (if the server response so
denied content are denied to be cached.

If you are asking how to make Squid cache dynamically generated then
there is two approaches:

a) Correct the content generator to include appropriate cachability
headers (i.e. a Expires or Cache-Control: min-age header). This also has
the added benefit that the content is cached by browsers and proxies,
which may give a trmendeous speed increase to your users (all depending
on the application).

b) Use the refresh_pattern settings in Squid to change the heuristics of
Squids dynamic expiry calculation used on content without a explicit
expiry time.
