Clone Pool Irule

What isn't clear when using an irule to set the clone pool conditionally is if it is setting the request side or the response side cloning. There only seems to be one iRule command to set cloning and it doesn't describe which it does or if it does both, or if it is based on the event where it appears.

 

 

i'll probably do a bunch of trial and error to find out, but if someone knows or if there is a document that provides the answer, it would be much appreciated!
