Setting XDebug session ID

xdebug.js

function setXdebugSessionCookie(sessionId) { 
  var now = new Date();
  var time = now.getTime();
  var expireTime = time + 1000*36000;
  now.setTime(expireTime);
  document.cookie = 'XDEBUG_SESSION='+sessionId+';expires='+now.toGMTString()+';path=/';
  console.log(document.cookie);
}

//Use: Assuming your session id for XDebug is 12345, then setting the cookie setXdebugSessionCookie(12345) will allow to debug AJAX calls.
