I have get a login page code on the web based on express nodeJS.

I have many backend app running on different port. The goal is, when a user is authentificated in the nodeJS server, he's automaticaly redirected to his app.

But, if i can mount a http-proxy separated and run it properly, i would want to include proxying in this loggin JS code when user is connected.

There is the part of the code below.

const httpProxy = require('http-proxy');
const proxy = httpProxy.createProxyServer();

(...)

// http://localhost:3000/auth
app.post('/auth', function(request, response) {
    // Capture the input fields
    let username = request.body.username;
    let password = request.body.password;
    // Ensure the input fields exists and are not empty
    if (username && password) {
        // Execute SQL query that'll select the account from the database based on the specified username and password
        connection.query('SELECT * FROM accounts WHERE username = ? AND password = ?', [username, password], function(error, results, fields) {
            // If there is an issue with the query, output the error
            if (error) throw error;
            // If the account exists
            if (results.length > 0) {
                // Authenticate the user
                request.session.loggedin = true;
                request.session.username = username;
                // Redirect to home page

                proxy.web(req, res, { target: 'http://127.0.0.1:1881' });

                //response.redirect('/home');
            } else {
                response.send('Incorrect Username and/or Password!');
            }           
            response.end();
        });
    } else {
        response.send('Please enter Username and Password!');
        response.end();
    }
});
app.listen(3000);

At the response.redirect('/home');i want to replace it by proxying, but nothing append.

I don't know if this is possible, because running 2 servers on the same instance.

Thank you for your help.
