title: get result from other controller of another application
body: <p>Is it possible to get result from a controller that is on another application.</p>
  
  <p>So I have a controller in application A, I want to get a result from another controller that is in application B.</p>
  
  <p>Or maybe, a simpler question: how to make REST call between controllers of different application?</p>
  
  <p>For example I want to get an ID at www.web2.com/index.php?r=controller2/action2
  the caller controller is at www.web1.com.</p>
  
  <p>Thank you</p>
