I want to block visitor between 2 to 5 minutes every 100 view.. if user view 100 page between 2 to 5 minutes then block user, if user view 100 view in 6 minutes then don't block and reset the counter.

I already create the counter script but i have issue with creating the function which can block visitor between 2-5 mint.

I need help to fix this problem... I try to create a if condition but no luck.. help me please...
