irule for load balancing to particular pool member based on maximum number of http requests

I would request if you can publish the exact irule with the syntax so that i can test the same.

The requirement is for the first 1000 HTTP Get requests, the virtual server should load balance the traffic to the first pool member 10.10.10.1 and if the traffic exceed 1000, then it should load balance the same to the second pool member or node 10.10.10.2.

Again after 2000th connection, counter should be set to 0 and as usual the next 1000 should go to 10.10.10.1 and go to 10.10.10.2 once the request is more than 1000 requests
