title: asp.net mvc session for a user can they open multiple tabs? multiple browsers?
body: <p>I am a bit confused on how ASP.NET session works with my site, when a user opens up the site in multiple browsers, and/or multiple tabs.</p>
  
  <p>I see that after logging in with IE, i can open a new tab and not have to log in, and that if I log out of one tab, the other one will redirect to login after I try to do something.</p>
  
  <p>I also notice that if I log in with IE, i still have to log in with FF.</p>
  
  <p>My question - are session data shared between all of these sessions?</p>
  
  <p>Are there any concerns I need to take into account here?</p>
  
  <p>Thanks!!!</p>
