Hi,
You have to implement some kind of countingmechanism when the page starts.
You can store the timestamp (now) in a database once the page runs, and
check if it has been accessed more than X times last Y seconds.
Just build it. :-)
Of course this check will slow down each request to the page a little, but
if the load of running the whole page is much higher, this may be worth the
time.
