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.

@julian He abandoned me. Please tell me what to do step by step to get something similar. Thanks!

@julian thanks, but I do not understand what is that. My webmaster helped me with the PHP code, but I'm not a programmer, and he does not use Node.js.
can you please paste the code conversion so that I can place it in my index.js

@julian I'm newbie to Node.js, lol so I don't really understand what do I have to do after I enabled the plugin on my NodeBB.

I can't get to translate this piece of code to place it in my NodeBB. I'd be thankful if yoy guys can help out!

<? session_set_cookie_params(0, '/', '.site.net');
     session_start();
     if(!isset($_SESSION["auth_token"])) {
     $_SESSION["auth_token"] = bin2hex(random_bytes(16));
     $full_url = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
     header("Location: https://secure.site.net/auth/$_SESSION[auth_token]?return_url=".$full_url);
     }
?>
