NimbostratusProper presistance configuration
We are experencing some issues with presistance where it looses presistance when we are using Round Robin. I was hoping to get exact details on what is the proper setup for this to work. Any help is appreciated. Please see below for overview of the config. We have tried several methods but none of them seem to work as described. So I'm thinking there is some setting we are missing. Thanks!

I'm guessing you're losing persistence on the Weblogic pair only? May I ask what the Apache pair is doing? 
Greg_33932They are providing protection in our DMZ. Yes, it seems to loose its session state between the Apache and 2nd F5 pair.
I did not want to confuse the config as I'm looking for a decent how-to on the presistance as I suspect we are missing some specific setting. Technically the config is:
Clients --> | Firewall | --> F5's --> Apache's --> | Firewall | --> F5's --> WL's- Kevin_StewartDual-tier environments are always tricky in terms of persistence. I believe the "official" BMC Remedy config for load balanced services recommends source address affinity for the lower tier (RP) resources. While that would definitely work here, it doesn't provide the most even distribution of load to the lower tiers machines.
I haven't done this in awhile, but try creating custom cookie persistence profiles for each VIP that uses a different cookie name, them verify that the client gets both.
