Proxy and Engine sessions

[AG-gugelbisolutions]

Hi there, I still have some doubts concerning proxy and engine sessions.

Question#1: I know they are different, but are they related?

Question #2: I'm playing around with Engine JSON API and it seems like I'm always creating or getting attached to the same session (ID = 1), even though a changed user and app ID; what am I getting wrong?

const session = enigma.create({
  schema,
  url: `wss://${engineHost}:${enginePort}/app/${appId}`,
  createSocket: (url) => new WebSocket(url, {
    ca: [readCert('root.pem')],
    key: readCert('client_key.pem'),
    cert: readCert('client.pem'),
	servername: 'ourServerName',
    headers: {
      'X-Qlik-User': `UserDirectory=${encodeURIComponent(userDirectory)}; UserId=${encodeURIComponent(userId)}`,
    },
  }),
});

//console.log(session);
//console.log(appId);

session.open().then((global) => {
	console.log(`Session was opened successfully for app ${appId}`);
	console.log(session.id);
	
	global.openDoc(
		`${appId}`
	)
	.then( (app) => {
		//console.log('App %d was open',app.qGenericId);
		console.log(`Opened app ${app.id}`);
		console.log(global.GetAuthenticatedUser());
		app.session.close();
		console.log(`Session was closed for app ${appId}`);
	})
	.catch( (error) => {
		if( error.message.includes("App already open") ) {
			console.log('INFO: the app is already open');
		} else {
			console.log('An error occurred while opening Qlik Sense app %d:','`${appId}`', error);
			process.exit(1);
		}
	})
	;

}).catch((error) => {
	console.log('An error occurred while opening Qlik Sense Engine session:', error);
	process.exit(1);
});
