Persistence Pool Member

Hi there,

I am trying to implement a canary deployment for my business' applications.

To do this I have the following:

Pool A

Node1 - ratio 4

Node2 - ratio 4

Node3 - ratio 4

Node4 - ratio 4

CanaryNode1 - ratio 2

I am currently using an iRule to route traffic to respective pools. Is there a way to set up persistence but just for the canary node? Or can I distribute traffic to 2 pools with a ratio through an irule - one pool a canary and the other containing standard nodes?

The standard nodes cannot be persistent.

Any help would be much appreciated.
