A value stored in the session DB from an iRule on the parent virtual server cannot be accessed from the internal virtual server, and vice-versa.
The session table cannot be used to pass data between virtual server and the internal virtual server.
This occurs when the following conditions are met: -- Virtual server with request-adapt or response-adapt profile. -- Internal virtual server referenced by adapt profile. -- iRules share data between the virtual server and the internal virtual server via session table.
If failover is not required, set the traffic group of the virtual address of the parent virtual server to 'traffic-group-local-only' which is the default existing on the internal virtual server. Here is an example command: tmsh modify ltm virtual-address 10.10.1.12 traffic-group traffic-group-local-only.
