But the bad thing about this is that if the relative path is not in the same folder, then the style will be a problem, and then another way

protected void Page_Load (object  sender, EventArgs e) {if(session["UserId"]= =null)   {Response.Write ("<script>alert" (" you are not logged in, Or login is invalid, please log in again "); top.location.href=". /login.html";</script>");}}
