You can use DTML scripting to set HTTP Response headers -
it sounds like you just need to add a snippet of DTML in
with your call to the counter which sets appropriate caching
headers for the client (note that "appropriate" varies by
client -- you'll probably need a few different cache headers
to ensure that most clients will understand one of them).
