title: Logout all open tabs automatically when user logs out in one of them
body: <p>I have created Login page, based on localStorage.
  On loading the page I have checked the value of localStorage.
  If I opened the web page in more than one tab and then I logout from any one of the tabs, all the remaining pages should logout automatically.</p>
  
  <p>If reload/refresh means it logging out.</p>
  
  <p>Please help me to run a script, when user view the page or say any other way to solve this problem.</p>
