Clone pool with two servers

Hi,

 

clone pool doesn't seem a very well documented feature so I didn't found anything about it. We have the requirement to clone serverside traffic to TWO servers. To put two servers in the clone pool shouldn't be an issue, but how does the LB behave? Will it really be send out twice to each server or only to one of them? And if just to one server, always to the same or based on Round Robin?

 

Is this possible at all?

 

Thank you!

 

Ciao Stefan :)
