IE and other multi-tab browser in a tab login after a new tab open the same URL how to determine that you have logged in to the landing page

Asked this question before, but feel that the answer is not complete, see Hotmail is login to a tab, after opening the new tab and then jump to the login page. How is it implemented?

Reply to discussion (solution)

The newly opened tab is equivalent to refreshing the page.
Session and other login information if it has been recorded, refresh the page is not to enter the login page,

I tried, I can't get to ssion, please explain upstairs, thank you.

To see the version of your browser.

IE8, I use the same browser to log on to my own system and Hotmail results are different, login Hotmail when I open a tab login, and then open a tab access Hotmail directly on the jump login.

No one knows?

Don't know what problem you're having, at least you didn't describe it clearly
You can test it like this.
setcookie.php

!--? Phpsession_start (); Setcookie (' name ', ' my ');   getcookie.php 
!--? Phpsession_start ();p rint_r ($_cookie); echo session_id ();  
 executes setcookie.php 
 in the first tab and then executes getcookie.php in the second tab 
 See what results
