Hi @HOUSSEM MAHJOUBI ,

As far as I think.it's impossible to check if the tab is closed. When the user request to the server,the server will get connected status.But the server couldn't know when the user disconnected. You need to learn more about Request.

Hi @HOUSSEM MAHJOUBI ,
As far as I think,there's no way to remotely monitor users. I think,you could use cookie and session to check if the user log in or log out.

Hi @HOUSSEM MAHJOUBI ,
Whenever any data is saved into the Session, the ASP.NET_SessionId cookie is created in the user’s browser. Even if the user has logged out (means the Session data has been removed by calling the Session.Abandon() or Session.RemoveAll() or Session.Clear() method), this ASP.NET_SessionId cookie and its value is not deleted from the user browser.You could learn more about cookie and session.
