Hi.
Do you really think preventing the browser from caching the page is what you
need here? I think no.
Whenever the page is shown/reloaded you need to check if the user already
has been "counted". This may be done by setting some information in a cookie
(you mentioned one). The code for your counter just has to get that
information and increase when not set.
Or did I get something wrong?
