Answer 1

To check your log in session,change the value of session time out in settings of applications. Keep it to some 3-5 minutes so that you can test it quickly. for that time do not perform any action and after some try to access your tool.you must be logged off of you application.

Answer 2

You may set a cookie when login is successful:

Response.Cookies.Add(new HttpCookie("login_status", "1"));

And when user presses "Log out", you either delete the cookie or set it to another value:

Response.Cookies.Add(new HttpCookie("login_status", "0"));

Then it's easy to check in Page_Load event of the login page:

HttpCookie loginStatusCookie = Request.Cookies["login_status"];
if(loginStatusCookie != null && loginStatusCookie.Value == "1")
{
     //User did not log out explicitly.
     //Display timeout message.
}
else
{
     //User either logged out or it is his/her first visit.
     //Display usual greeting.
}
