Client persistance through 2 VS in a single request

Consider the following situation:

 

1) A virtual server is configured that passes traffic from a client to a pool of servers that provide authentication and authorization. Once authorization is complete, these servers will proxy all traffic to a secondary VIP (the target application) on every request.

 

2) Once the client is authenticated, The pool members of the first VIP send the clients request to a second VIP to connect to the application. This application also includes a session ID that must be persisted.

 

3) In order for the connection to function correctly with the application behind the second VIP, persistence must be maintained with the original client.

 

How can session persistence be maintained when the client IP is manipulated in this manner? I read the descriptions for the persist across pool members / virtual servers setting available within the persistence options, but it didn't seem to be appropriate for this situation

 

Client persistence with original client and pool member 2 of Vip 2.

 

Client -> VIP -> Pool member -> Vip 2 -> Pool member2

 

Any ideas?
