"<%= System.Configuration.ConfigurationSettings.AppSettings["SessionWarning"].ToString()%>";

I dont have idea to work outso plz help ,

What I have tried:

<configuration>
  <appSettings>
  <add key="isatdatapro.GatewayInterface" value="https://localhost:4433/GLGW/GWServices_v1/Messages.svc"/>
  </appSettings>
  <system.web>
    <sessionState mode="InProc" timeout="20"></sessionState>
    <trust level="Full"/>
    <customErrors mode="Off"/>
    <compilation debug="true" targetFramework="4.0">
      <assemblies>
        <add assembly="System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add assembly="System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
        <add assembly="System.Web.Extensions.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add assembly="System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
      </assemblies>
    </compilation>
  </system.web>
</configuration>

   var sessionTimeoutWarning =
    "<%= System.Configuration.ConfigurationSettings.AppSettings["SessionWarning"].ToString()%>";
        var sessionTimeout = "<%= Session.Timeout %>";

        var sTimeout = parseInt(sessionTimeoutWarning) * 60 * 1000;
        setTimeout('SessionWarning()', sTimeout);

        function SessionWarning() {
var message = "Your session will expire in another " +
    (parseInt(sessionTimeout) - parseInt(sessionTimeoutWarning)) +
    " mins! Please Save the data before the session expires";
alert(message);
        }
