// Usage Example for createProxyServer

// Specify the port number, target URL, SSL certificate path, and private key path
const port = 8080;
const targetUrl = 'http://example.com';
const certificatePath = '/path/to/certificate.pem';
const privateKeyPath = '/path/to/privatekey.pem';

// Create the proxy server
createProxyServer(port, targetUrl, certificatePath, privateKeyPath);
