how to store the values in server using redis db and retrieve the same in client?

Hi am using Redis Database for my application, i wanna send some values from client to server-side and have to retrieve the same from server to another client side, i can use set & get in server-side, But i stuck in retrieving the value, anybody help me retrieving the value in client-side.

socket.on('get_position', function (height,width,pHeight, pWidth,val) { socket.broadcast.emit("changeSize",height,width, pHeight,pWidth,val);
}); 

In the above part of the code, am getting the changes in client side and broadcasting to other clients with the helpof session store(FYI : get_position: it will get the position of the widget from the client side,changeSize: will reflect this position to other clients).

Now, I stored using redis, how to retrieve that in client.
