Stateless session persistence

I didn't think this was the case because the persistence profile has a "mirror persistence" option. (I don't have any way of verifying this because I only have one BIG-IP at the moment [expecting more this week, hopefully].)

 

 

Still, though, I'd like to have more control over what happens with the cookies, so I may still decide to use a universal persistence profile.

 

 

What is the correct way to select a node in a rule attached to a universal persistence profile? Is it "LB::reselect $pool $node", "node $node", "pool $pool member $node", or something else??

 

 

Presumably I would also need some logic to handle disabled/forced-offline nodes? Do I really need to reimplement all this logic if I want to use a universal persistence profile?

 

 

Is there an example somewhere of, say, implementing a cookie-insert persistence profile in iRules?

 

 

 

Thanks!
