title: Track another Tab in the same browser
body: <p>I am building a time tracking application for my organisation.
  I have a website ready and launched with the AUX and Breaks to punch, let's name it AUXY. Now I need to take data from another website(In different tab of same browser) let's name it LAYS. If one goes active/away on the LAYS, how can I detect that.</p>
  
  <p>Currently I'm scraping Dashboard of LAYS which takes up a lot of time as all the employee's details are fetched and there is a delay of 1 min 30 sec. I need to make it real-time.</p>
  
  <p>Is there a way to track the active/away activity of LAYS from AUXY, as they will be open in the same Browser? AUXY is developed using PHP and JavaScript.</p>
