@DavidSchinazi, from this I infer that pre-caching values is not feasible.  Perhaps your load balancers integrate the client address in their decisions.  Is that right?

An alternative is to alter the ODCID transport parameter to integrate the SCID from the Retry.  Another would be to require that the server perform a check based on the Retry token (as mentioned).
