Clone, what does it do technically in an iRule?

Hey thanks for the reply, unfortunately I have read that piece about 10 times already and I still have the questions I raised above. I am not a network engineer, I am a developer that got pushed into working on the F5 because I know a bunch of programming languages and I understand networking fairly well. I actually really enjoy working on iRules but in this case I do not understand exactly what is *supposed* to happen with clone pools in the VS and the clone command in an iRule. I really need a duplicate request sent to another pool. I see packets going to the pool but not a duplicate request. There is not a wealth of info about clone.
