Using two uno board and Wifi-shield

Hey guys!
i have a question.
My question is, is it possible to use two uno boards and one wifi-shield(official one) at the same time?
one uno board will be directly connected to Wifi-shield and the other uno board want to be connected to the same wifi-shield using wires.
I don't know whether this system will work or not.
any advice?
Thank you !

What is the purpouse of having two arduinos? Extra IO? Why not communicate the two arduinos as master slave, and let the master handle wifi?
