title: Facebook AppRequest handle on unity3d game
body: <p>I am trying to make a game in Unity3D with new facebook unity sdk. I am able to send an AppRequest to the friends in my list. But my doubt is, after my friends has downloaded the same game, how can I communicate with friends using the AppRequest. </p>
  
  <p>For eg. If I am sending a "Life" to the friend, my friend should see a "Life" sent from me in his game. his "Life" counter should get incremented by 1 (life++). Same thing with "Ammo" can be done.</p>
  
  <ol>
  <li>Sender   : How to differentiate the "Life request" and "Ammo Request".</li>
  <li>Receiver : In game, how to get that request and differentiate it, so that "Life" or "Ammo" counters gets incrementation.</li>
  </ol>
