PHP Code to Node.js Code Conversion

[pabloc]

I have the following piece of code:

session_set_cookie_params(0, '/', '.site.net');
session_start();
if(!isset($_SESSION["auth"])) {
  $_SESSION["auth"] = true;
  header("Location: https://secure.site.net/auth?return_url=https://forums.site.net$_SERVER[REQUEST_URI]");
}

How can I convert this to Node.js and where should I place it so that all requests to my NodeBB forum pass through this? I can't figure out how to do this.
