The BIG-IP persistence cookie is an encoded (not encrypted) form of the pool member IP and port. The cookie name by default is BIGipServer. The encoding is described in SOL6917 (Click here). This codeshare example (Click here) shows how to decode it in an iRule.

 

 

Are you trying to generate a unique ID for handling sessions or for persistence? If the former, I could see why you'd want to prevent collisions. If the latter, I'm not so clear. Can you explain why you would need a globally unique token for persistence? Why couldn't you just the default cookie insert persistence with a expiration time set according to your requirements? I don't understand why the persistence cookie would need to be globally unique if you're just trying to give the client a token with which you get them back to the same pool member.
