User Sessions Timing Out Too Early

[Mypeinisy]

&nbsp;<BR>My asp.net user sessions keep timing out on me after about fifteen minutes -- even though my last click was a minute before. I thought they time out only started a countdown after the most recent click -- not from the start of the session?<BR><BR>Anyway, my global.aspx is below. Do I have it set incorrectly?<BR><BR><script language="VB" runat="server"><BR><BR>Sub Session_Start(Sender As Object, E As EventArgs)<BR>'Session ("Start") = DateTime.Now.ToString<BR>'Response.Write("Session is starting...<BR>")<BR>'Response.write (session.sessionid)<BR><BR>Session("count")=0<BR>Session.timeout=180<BR><BR>End Sub<BR><BR>Sub Session_End(Sender as Object, E As EventArgs)<BR>'do nothing<BR>End Sub<BR></script><BR>
