This works for me

<session-management invalid-session-url="/taac/login">
    <concurrency-control max-sessions="1" error-if-maximum-exceeded="true" />
</session-management>

Here's how I typically do it. On every AJAX call, check the result before using it.

$.ajax({ type: 'GET',
    url: GetRootUrl() + '/services/dosomething.ashx',
    success: function (data) {
      if (HasErrors(data)) return;

      // process data returned...

    },
    error: function (xmlHttpRequest, textStatus) {
      ShowStatusFailed(xmlHttpRequest);
    }
  });
And then the HasErrors() function looks like this, and can be shared on all pages.

function HasErrors(data) {
  // check for redirect to login page
  if (data.search(/login\.aspx/i) != -1) {
    top.location.href = GetRootUrl() + '/login.aspx?lo=TimedOut';
    return true;
  }
  // check for IIS error page
  if (data.search(/Internal Server Error/) != -1) {
    ShowStatusFailed('Server Error.');
    return true;
  }
  // check for our custom error handling page
  if (data.search(/Error.aspx/) != -1) {
    ShowStatusFailed('An error occurred on the server. The Technical Support Team has been provided with the error details.');
    return true;
  }
  return false;
}

If this is useful mark it as solution
With Regards............
