Yes.

See refresh_pattern.

But please note that in such case there is very limited benefit of using
a cache. The overhead of a conditional GET is the same as a plain GET,
and the biggest benefit of a cache is to be able to avoid this overhead
in latency time. This overhead is also a quite significant portion of
the bandwidth usage of HTTP.
