public ActionResult Index(string state, string code)
{
    try
    {
        IAuthenticator authenticator = Utils.GetCredentials(code, state);
        // Store the authenticator and the authorized service in session
        Session["authenticator"] = authenticator;
        Session["service"] = Utils.BuildService(authenticator);
    }
    catch (CodeExchangeException)
    {
        if (Session["service"] == null || Session["authenticator"] == null)
        {
            Response.Redirect(Utils.GetAuthorizationUrl("", state));
        }
    }
    catch (NoRefreshTokenException e)
    {
        Response.Redirect(e.AuthorizationUrl);
    }

    DriveState driveState = new DriveState();

    if (!string.IsNullOrEmpty(state))
    {
        JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
        driveState = jsonSerializer.Deserialize<DriveState>(state);
    }

    if (driveState.action == "open")
    {
        return OpenWith(driveState);
    }
    else
    {
        return CreateNew(driveState);
    }
}
