IE and other multi-TAB browsers log on to one TAB and then open a new TAB to open the same Web site. how can I determine if I have logged on to the login page?

IE and other multi-TAB browsers log on to a TAB and then open a new TAB to open the same Web site. how can I determine whether I have logged on to the login page and asked this question before? However, I think the answer is incomplete, after you log on to a TAB in hotmail, the new tab is displayed on the logon page. How to implement it?

The new tab refreshes the page.
If the session and other logon information have been recorded, do you enter the logon page after refreshing the page,

I tried and couldn't get the SSION. please explain it upstairs. thank you.

Check the version of your browser.

In IE8, I use the same browser to log on to my system and the result of hotmail is different. when I log on to hotmail, I open a TAB to log on. then I open a tab to access hotmail and jump to the logon page.

No one knows?

I don't know what problems you have encountered. at least you have not clearly described them.
You can test it like this.
Setcookie. php

 Getcookie. php
    
First, execute setcookie. php in the first TAB.
Then execute getcookie. php in the second TAB.
Let's take a look at all the results.
 
 
The problem I encountered was that I logged on to the system in a TAB browser, and then opened the same address in the tab of the same browser, and the logon status appeared. after I logged on with different accounts, the previously logged-on account is changed to the logged-on account.
 
The new version of ie seems to be multi-session, but in addition to online banking, I haven't used ie for a long time, so I haven't studied it.
