+```

 ## Usage

-`@push.rocks/smartproxy` is a comprehensive package that provides advanced functionalities for handling proxy tasks efficiently, including SSL redirection, port proxying, WebSocket support, and dynamic routing with authentication capabilities. Here is an extensive guide on how to utilize these features effectively, ensuring robust and secure proxy operations.
-
-### Initial Setup
-
-Before exploring the advanced features of `smartproxy`, you need to set up a basic proxy server. This setup serves as the foundation for incorporating additional functionalities later on:
+### Basic Reverse Proxy Setup

 ```typescript
 import { NetworkProxy } from '@push.rocks/smartproxy';

-// Create an instance of NetworkProxy with the desired configuration
-const myNetworkProxy = new NetworkProxy({ port: 443 });
+// Create a reverse proxy listening on port 443
+const proxy = new NetworkProxy({
+  port: 443
+});

-// Define reverse proxy configurations for the domains you wish to proxy
+// Define reverse proxy configurations
 const proxyConfigs = [
  {
-    destinationIp: '127.0.0.1',
-    destinationPort: '3000',
    hostName: 'example.com',
-    privateKey: `-----BEGIN PRIVATE KEY-----
-PRIVATE_KEY_CONTENT
-----END PRIVATE KEY-----`,
-    publicKey: `-----BEGIN CERTIFICATE-----
-CERTIFICATE_CONTENT
-----END CERTIFICATE-----`,
+    destinationIp: '127.0.0.1',
+    destinationPort: 3000,
+    publicKey: 'your-cert-content',
+    privateKey: 'your-key-content'
  },
-  // Additional configurations can be added here
+  {
+    hostName: 'api.example.com',
+    destinationIp: '127.0.0.1',
+    destinationPort: 4000,
+    publicKey: 'your-cert-content',
+    privateKey: 'your-key-content',
+    // Optional basic auth
+    authentication: {
+      type: 'Basic',
+      user: 'admin',
+      pass: 'secret'
+    }
+  }
 ];

-// Start the network proxy to enable forwarding
-await myNetworkProxy.start();
-
-// Apply the configurations you defined earlier
-await myNetworkProxy.updateProxyConfigs(proxyConfigs);
-
-// Optionally, you can set default headers to be included in all responses
-await myNetworkProxy.addDefaultHeaders({
-  'X-Powered-By': 'smartproxy',
-});
+// Start the proxy and update configurations
+(async () => {
+  await proxy.start();
+  await proxy.updateProxyConfigs(proxyConfigs);
+  
+  // Add default headers to all responses
+  await proxy.addDefaultHeaders({
+    'Strict-Transport-Security': 'max-age=31536000; includeSubDomains; preload'
+  });
+})();
 ```

-### Configuring SSL Redirection
-
-A critical feature of modern proxy servers is the ability to redirect HTTP traffic to secure HTTPS endpoints. The `SslRedirect` class in `smartproxy` simplifies this process by automatically redirecting requests from HTTP port 80 to HTTPS:
+### HTTP to HTTPS Redirection

 ```typescript
 import { SslRedirect } from '@push.rocks/smartproxy';

-// Create an SslRedirect instance to listen on port 80
-const mySslRedirect = new SslRedirect(80);
-
-// Start the redirect to enforce HTTPS
-await mySslRedirect.start();
-
-// To stop HTTP redirection, use the following command:
-await mySslRedirect.stop();
+// Create and start HTTP to HTTPS redirect service on port 80
+const redirector = new SslRedirect(80);
+redirector.start();
 ```

-### Managing Port Proxying
-
-Port proxying is essential for forwarding traffic from one port to another, an important feature for services that require dynamic port changes without downtime. Smartproxy's `PortProxy` class efficiently handles these scenarios:
+### TCP Port Forwarding with Domain-based Routing

 ```typescript
 import { PortProxy } from '@push.rocks/smartproxy';

-// Set up a PortProxy to forward traffic from port 5000 to 3000
-const myPortProxy = new PortProxy(5000, 3000);
-
-// Initiate the port proxy
-await myPortProxy.start();
-
-// To halt the port proxy, execute:
-await myPortProxy.stop();
-```
-
-For more intricate setups—such as forwarding based on specific domain rules or IP allowances—smartproxy allows detailed configurations:
-
-```typescript
-import { PortProxy } from '@push.rocks/smartproxy';
-
-// Configure complex port proxy rules
-const advancedPortProxy = new PortProxy({
-  fromPort: 6000,
-  toPort: 3000,
-  domains: [
+// Configure port proxy with domain-based routing
+const portProxy = new PortProxy({
+  fromPort: 443,
+  toPort: 8443,
+  targetIP: 'localhost', // Default target host
+  sniEnabled: true,      // Enable SNI inspection
+  globalPortRanges: [{ from: 443, to: 443 }],
+  defaultAllowedIPs: ['*'], // Allow all IPs by default
+  domainConfigs: [
    {
-      domain: 'api.example.com',
-      allowedIPs: ['192.168.0.*', '127.0.0.1'],
-      targetIP: '192.168.1.100'
+      domains: ['example.com', '*.example.com'], // Glob patterns for matching domains
+      allowedIPs: ['192.168.1.*'],               // Restrict access by IP
+      blockedIPs: ['192.168.1.100'],             // Block specific IPs
+      targetIPs: ['10.0.0.1', '10.0.0.2'],       // Round-robin between multiple targets
+      portRanges: [{ from: 443, to: 443 }]
    }
-    // Additional domain rules can be added as needed
  ],
-  sniEnabled: true,  // Server Name Indication (SNI) support
-  defaultAllowedIPs: ['*'],
+  maxConnectionLifetime: 3600000, // 1 hour in milliseconds
+  preserveSourceIP: true
 });

-// Activate the proxy with conditional rules
-await advancedPortProxy.start();
+portProxy.start();
 ```

-### WebSocket Handling
-
-With real-time applications becoming more prevalent, effective WebSocket handling is crucial in a proxy server. Smartproxy natively incorporates WebSocket support to manage WebSocket traffic securely and efficiently:
-
-```typescript
-import { NetworkProxy } from '@push.rocks/smartproxy';
-
-// Create a NetworkProxy instance for WebSocket traffic
-const wsNetworkProxy = new NetworkProxy({ port: 443 });
-
-// Define proxy configurations targeted for WebSocket traffic
-const websocketConfig = [
-  {
-    destinationIp: '127.0.0.1',
-    destinationPort: '8080',
-    hostName: 'socket.example.com',
-    // Include SSL details if necessary
-  }
-];
-
-// Start the proxy and apply WebSocket settings
-await wsNetworkProxy.start();
-await wsNetworkProxy.updateProxyConfigs(websocketConfig);
-
-// Set heartbeat intervals to maintain WebSocket connections
-wsNetworkProxy.heartbeatInterval = setInterval(() => {
-  // Logic for connection health checks
-}, 60000); // every minute
-
-// Capture and handle server errors for resiliency
-wsNetworkProxy.httpsServer.on('error', (error) => console.log('Server Error:', error));
-```
-
-### Advanced Routing and Custom Features
-
-Smartproxy shines with its dynamic routing capabilities, allowing for custom and advanced request routing based on the request's destination. This enables extensive flexibility, such as directing API requests or facilitating intricate B2B integrations:
-
-```typescript
-import { NetworkProxy } from '@push.rocks/smartproxy';
-
-// Instantiate a proxy with dynamic routing
-const routeProxy = new NetworkProxy({ port: 8443 });
-
-routeProxy.router.setNewProxyConfigs([
-  {
-    destinationIp: '192.168.1.150',
-    destinationPort: '80',
-    hostName: 'dynamic.example.com',
-    authentication: {
-      type: 'Basic',
-      user: 'admin',
-      pass: 'password123'
-    }
-  }
-]);
-
-// Activate the routing proxy
-await routeProxy.start();
-```
-
-For those who require granular traffic control, integrating tools like `iptables` offers additional power over network management:
+### IPTables Port Forwarding

 ```typescript
 import { IPTablesProxy } from '@push.rocks/smartproxy';

-// Set up IPTables for sophisticated network traffic management
-const iptablesProxy = new IPTablesProxy({
-  fromPort: 8081,
+// Configure IPTables to forward from port 80 to 8080
+const iptables = new IPTablesProxy({
+  fromPort: 80,
  toPort: 8080,
-  deleteOnExit: true // Clean up rules when the server shuts down
+  toHost: 'localhost',
+  preserveSourceIP: true,
+  deleteOnExit: true  // Automatically clean up rules on process exit
 });

-// Enable routing through IPTables
-await iptablesProxy.start();
+iptables.start();
 ```

-### Integrating SSL and HTTP/HTTPS Credentials
-
-Handling sensitive data like SSL keys and certificates securely is crucial in proxy configurations:
+### Automatic HTTPS Certificate Management

 ```typescript
-import { loadDefaultCertificates } from '@push.rocks/smartproxy';
+import { Port80Handler } from '@push.rocks/smartproxy';

-try {
-  const { privateKey, publicKey } = loadDefaultCertificates(); // Adjust path if necessary
-  console.log('SSL certificates loaded successfully.');
-  // Use these credentials in your configurations
-} catch (error) {
-  console.error('Error loading certificates:', error);
-}
+// Create an ACME handler for Let's Encrypt
+const acmeHandler = new Port80Handler();
+
+// Add domains to manage certificates for
+acmeHandler.addDomain('example.com');
+acmeHandler.addDomain('api.example.com');
 ```

-### Testing and Validation
+## Configuration Options

-Smartproxy supports extensive testing to ensure your proxy configurations operate as expected. Leveraging `tap` alongside TypeScript testing frameworks supports quality assurance:
