UDP is connectionless and there for it has no sessions from a network protocol point of view.

 

It sounds like the application may have a "session", if so, then there is something that MUST be included in each message that identifies which "session" that message is part of. So as long as your iRule is looking that the correct part of the message, it should work. The only think you might need to look at is how long you keep the persist record around. By default it is 3 minutes after the last reference. So without any time value on your persist command, 3 minutes after the last reference. How long are the "sessions" supposed to last?
