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

i m only looking at a simple irule which can be used to that the first 1000 connection is exceeded then only it should be redirected to the second pool member.

you can count number of active connections using table command. it could be similar to this (you have to revise it because the example counts number of active connections for each client ip).

to send traffic to specific pool member, you can use pool or node command.
