persistence profile and two vip
Hi community
I have a special use case and hope someone has an idea.
I have to create an environment with F5 load balancer (round robin), persistence profile, snat (automap), two proxy for A/B testing and 5 application server.
In the picture below you see the flow of the connection
The goals:
- We have to use all the application server. Each server should have 20% of the load
- The customer session (session lifetime) have to land always on the same app server. So we need a persistence profile
- The proxy server and the application server are it the same network, so we configure snat (automap)
The question:
- Where do I have to configure the persistence profile? One the F5 Proxy Virtual Server or on the F5 App Virtual Server or both?
I configured two different cookie persistence profile on both virtual server. The persistence profile works but I always land only on two application server from 5. For testing we used a load testing tool with 20 different source IP, all the sessions land only one two application servers.
