    Session Question

    I'm tracking usersOnline by adding this code below in my Global.asax
    file.But i noticed that when a user logs in it keeps adding a new user
    which thats fine..but when a user logs of it still retains the
    user(session) for sometime instead of reducing it by one!

    I'm thinking of maybe i should change something in IIS relating to
    Session?

    Any ideas..


    Sub Session_Start(B yVal sender As Object, ByVal e As EventArgs)
    ' Fires when the session is started
    Session("Start" ) = Now
    Application.Loc k()
    Application("Ac tiveUsers") = CInt(Applicatio n("ActiveUsers" )) +
    1
    Application.UnL ock()
    End Sub

    --------------------------
    Sub Session_End(ByV al sender As Object, ByVal e As EventArgs)
    ' Fires when the session ends
    Application.Loc k()
    Application("Ac tiveUsers") = CInt(Applicatio n("ActiveUsers" )) -
    1
    Application.UnL ock()
    End Sub

      Re: Session Question

      By default a session ends after 20 minutes of no page requests from the
      user.
      That would be when the Session_End event normally fires.

          Thx Steve..
          So it means if i change the Session Timeout in Web.Config to a lower
          value it should be fine?

          And another question which one overrides Session timeout in Web.Config
          or IIS..

              Yes.
              It would also be fine if you change it to a higher value.

              re:[color=blue]

              Web.config overrides.

                      Lower would be more accurate for tracking users online, but it might annoy
                      your users if you set it too low.

                          That would depend on your user's needs
                          or on your website's needs.


                          Tracking sessions consumes server resources
                          ( memory and processing time, for the most part ).

                          If you need to track user information to such
                          an extent that you need a longer session level.
                          then increasing it would make sense.

                          Otherwise, increasing the session time
                          would be a waste of server resources.

                          You should strive for the least session time value
                          which serves your user/server needs.
