title: Laravel Session and multiple tabs
body: <p>I found out very interesting (at least for me) session behaviour while I tested my "log out" section:</p>
  
  <p>If I open two tabs in a browser and log in to my app with both of them (with same account credentials), then if I go to the first tab, press "log out" - it will remove my session variables and I will be logged out from both tabs. But when I do the opposite - if I log out from the second tab - the first tab remains logged in and my <code>Session::flush()</code> is not applying.</p>
  
  <p>May someone explain that behaviour and tell me how to control that. I want to remove my session variables no matter which tab is "logged out", not only the first.</p>
  
  <p>EDIT: </p>
  
  <p>Now I am expecting another issue - no matter which tab i "log out" - the other still remains logged in. Is it related with caching or something?</p>
