Opening a new tab will remove session in Chrome And Mozilla Browser but doesn't in IE and Edge
<p>I've a client code that set session with JavaScript and PHP, however beside logout or session timeout, there's no code calling function to remove session.</p>

<p>On page load(whichever page), it will check for session if no session, it will redirect to login page.</p>

<p>The problem now is in Mozilla or Chrome, after logged-in, when I open in new tab, it will redirect me to the login page, while open in same tab doesn't as session still remains.</p>

<p>However trying on IE and Edge browser, everything is fine.</p>

<p>I'm sorry I can't post clients code. So would just like to hear if anyone have similar issues that can share.</p>

<p>Thanks.</p>
