Solution 1

One approach to do this would be to check for ASP.NET_SessionId in the request.
This neat article[^] explains this approach.

Another approach could be to handle void Session_End(object sender, EventArgs e) in the global.asax file.

Hi,

If you have no other option rather than session then use the fallowing Code :

C#

public enum SessionKeys:int
{
Unknown=0,
LogInTime=1,
LogOutTime=2,
IsLoggedIn,3
}

After Log In :

C#

Session[SessionKeys.LogInTime.ToString()]=DateTime.Now;
Session[SessionKeys.IsLoggedIn.ToString()]=true;

After LogOut

C#

Session[SessionKeys.LogOutTime.ToString()]=DateTime.Now;
Session[SessionKeys.IsLoggedIn.ToString()]=false;

Now you can check the session key IsLoggedIn to know whether user is Logged in or not.

if Timeout happened then IsLoggedIn key would be null so your check should me not Null and Not False.
