with the hash cookie persistence I cannot decide based on the cookie of the 1st request to which pool member should I send the request. I think doing an irule with selectif load balancing based on received cookies from client is enough? or am I missing something?

    Regarding the decision about using cookie hash or cookie passive, both are similar and both could fit in your scenario (depend on your requirements).

    Anyway, all depends on what your decision is when the first request comes into play. What logic do you have in mind? base on this you could need an iRule or not.

     

    Take into account that when no persistence record is found, a new load balancing decision is made.
