Hi, thank you for your reply.
Yes I am talking about the session table, and I am able to add a value in an iRule on one virtual server and retrive that value in another iRule on a different virtual server, but when I call the second virtual server using the virtual command on the first virtual server I am not able to retrieve the value. I am not sure that the virtual command is related but this is the only difference between when it works and when it doesn't. I can not find anything to indicate there should be any issue doing this when using the virtual command.
