Can the browser tabs automatically detect when a user logs out?

When I have multiple tabs open of the same website in a browser, I wonder how other windows can detect when a user has logged out. My development setup involves using Python/Django.

The method I am currently implementing is:

function user_checking(){

         $.ajax({
            url: /check_user_login,
            type: 'POST',

            success: function (data) {

            if (data['user_status'] == 'not_loggedin'){
            location.reload(); 
            }

            },
            error: function (data) {
            },

         }); //ajax end
    }

    var validateSession = setInterval(user_checking, 1000);

To monitor whether the user is logged out or not, I am constantly sending the user_checking() function every second. Is this the correct approach?

Utilizing WebSocket technology in this scenario would be ideal.

The WebSocket API allows for real-time, two-way communication between a browser and server without the need to constantly poll for responses.

Since you are working with Django, I recommend checking out this article:

If WebSocket is not an option, your current solution should suffice for a small website. Alternatively, you could keep other tabs inactive until a request is made to the server, which would then indicate that the user is disconnected.
