Requests to Server

//well I'm doing a presence service with vert.x so I need to verify who are on my friend's list

//to do that I will need to contact my mongodb and need to know who is on my friends list and his state presence

//ONCLIENT
//this is my request to the module on the server from the client.

test => friends list [test3, test4, test5]
test2 => friends list [test6, test7, test8]

if both do the request to the server at the same time the answer to the test will be:
[{name: test3, statePresence: online}, {name: test4, statePresence: online}, {name: test5, statePresence: online}, {name: test6, statePresence: online},{name: test7, statePresence: online}, {name: test8, statePresence: online}]

and to test2:
[{name: test6, statePresence: online},{name: test7, statePresence: online}, {name: test8, statePresence: online}]
