I have one pressing issue that I need to find solution to.

I recently viewed my project work in chrome browser; I navigated to the login page I created and logged in using a user ID and password that exists in the database. In the dashboard page I right-clicked on a navigation link to navigate to another page, it worked. Then I had two tabs opened for the website. I later went to the previous tab, without closing the other, I logged out of the account and it logged out. But the issues is that I went to the other tab which was still open, and refreshed the page and it refreshed but the user was still logged in. I thought that when I had logged out of that particular account, it should have logged out completely so even when anybody refreshes it should have redirected to login page.

The most intriguing part is that I closed the tabs and opened a new tab by clicking on the “+” on the browser bar to open new tab, and I went to history and clicked to open the last page, it open to that page as logged in account, NOT redirecting to login page.

Here is my code to log out

if (Session["user"] == null)
{
    SqlConnection con = new SqlConnection("Data Source=(LocalDB)\\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\\Dataregister.mdf;Integrated Security=True");
    con.Open();
    string UpdateLog = @"UPDATE Users SET IsActive=@IsActive";
    using (SqlCommand cmd = new SqlCommand(UpdateLog, con))
    {
        cmd.Parameters.AddWithValue("@IsActive", "0");
        cmd.ExecuteNonQuery();
    }
    con.Close();
    Response.Redirect("LoginForm.aspx");
}

It's based on your code logic. Onces you logout you can update currentlogoutTime in database for particular user and on your generic method call to check wheather CurrentLogoutTime is less than currentTime if it less than then you can call Session.Abandon() to end the session for all browsers.

// On single page or on Masterpage
protected void Page_Load(object sender, EventArgs e)
{
    // Check the LogoutTime for User if its less than Current time then Make current session End using Session.Abandon();			       
}	  

// On Logout Event
protected void Logout(object sender, EventArgs e)
{
    Session.Abandon();
    // Update in your database in table where you can save CurrentLogouttime based on UserId
}

// If you have any BaseClass which you are inheriting for pageClass then call it in that page
protected void Page_PreInit(object sender, EventArgs e)
{				 
    // Check the LogoutTime for User if its less than Current time then Make current session End        
}

Also on Login You Need to make same Column value as Null which you have updated with CurrentDateTime based on UseId so it will allow user to be active as there is Null value.

protected void Login(object sender, EventArgs e)
{
    // Update in your database in table where you can Null the logouttime  based on UserId so it will make him as Active user
}
