iApp for Exchange CAS Load balance Method Doesn't Works for OWA Pool

Hi Mike,

Theoretically, yes, client should be load balanced again to pool member which has the least connection after "session" cookie ended, but currently client still no load balance to other pool member. I have tried with multiple clients with different browser accessed to OWA but still getting the same BIG-IP cookie value from LTM as shown at image below. What else possible cause the load balance didn't works properly. Thanks.
