 ## Usage

-`@push.rocks/smartproxy` is a versatile package for setting up and handling proxies with various capabilities such as SSL redirection, port proxying, and creating network proxies with complex routing rules. Below is a comprehensive guide on using its features.
+`@push.rocks/smartproxy` is a comprehensive and versatile package designed to handle complex and high-volume proxying tasks efficiently. It includes features such as SSL redirection, port proxying, WebSocket support, and customizable routing and authentication mechanisms. This guide will provide a detailed walkthrough of how to harness these capabilities effectively. 

-### Setting Up a Network Proxy
+### Initial Setup

-Create a network proxy to route incoming HTTPS requests to different local servers based on the hostname.
+Before diving into specific features, let's start by configuring and setting up our basic proxy server:

 ```typescript
 import { NetworkProxy } from '@push.rocks/smartproxy';
@ -26,7 +26,7 @@ import { NetworkProxy } from '@push.rocks/smartproxy';

-// Optionally, add default headers to all responses
+// Optionally add default headers to all responses
 await myNetworkProxy.addDefaultHeaders({
  'X-Powered-By': 'smartproxy',
 });
 ```

-### Port Proxying
+### Configuring SSL Redirection

-You can also set up a port proxy to forward traffic from one port to another, which is useful for dynamic port forwarding scenarios.
-
-```typescript
-import { PortProxy } from '@push.rocks/smartproxy';
-
-// Create a PortProxy to forward traffic from port 5000 to port 3000
-const myPortProxy = new PortProxy(5000, 3000);
-
-// Start the port proxy
-await myPortProxy.start();
-
-// To stop the port proxy, simply call
-await myPortProxy.stop();
-```
-
-### Enabling SSL Redirection
-
-Easily redirect HTTP traffic to HTTPS using the `SslRedirect` class. This is particularly useful when ensuring all traffic uses encryption.
+One essential capability of a robust proxy server is ensuring that all HTTP traffic is redirected to secure HTTPS endpoints. This can be effortlessly accomplished using the `SslRedirect` class within `smartproxy`. This class listens on port 80 (HTTP) and redirects all incoming requests to HTTPS:

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

-// Instantiate the SslRedirect on port 80 (HTTP)
+// Instantiate the SslRedirect for listening on port 80
 const mySslRedirect = new SslRedirect(80);

-// Start listening and redirecting to HTTPS
+// Start listening and redirect HTTP traffic to HTTPS
 await mySslRedirect.start();

-// To stop the redirection, use
+// To stop redirection, you can use the following command:
 await mySslRedirect.stop();
 ```

-### Advanced Usage
+### Handling Complex Networking with Port Proxy

-The package integrates seamlessly with TypeScript, allowing for advanced use cases, such as implementing custom routing logic, authentication mechanisms, and handling WebSocket connections through the network proxy.
+Port proxying allows redirection of traffic from one port to another. This capability is crucial when dealing with services that need dynamic port forwarding, or when adapting to infrastructure changes without downtime. Smartproxy's `PortProxy` class handles this efficiently:

-For a more advanced setup involving WebSocket proxying and dynamic configuration reloading, refer to the network proxy example provided above. The WebSocket support demonstrates how seamless it is to work with real-time applications.
+```typescript
+import { PortProxy } from '@push.rocks/smartproxy';

-Remember, when dealing with certificates and private keys for HTTPS configurations, always secure your keys and store them appropriately.
+// Create a PortProxy to directly forward traffic from port 5000 to 3000
+const myPortProxy = new PortProxy(5000, 3000);

-`@push.rocks/smartproxy` provides a solid foundation for handling high workloads and complex proxying requirements with ease, whether you're implementing SSL redirections, port forwarding, or extensive routing and WebSocket support in your network.
+// Initiate the port proxy
+await myPortProxy.start();

-For more information on how to use the features, refer to the in-depth documentation available in the package's repository or the npm package description.
+// To stop the port proxy mechanism:
+await myPortProxy.stop();
+```
+
+Additionally, smartproxy's port proxying can support intricate scenarios where different forwarding rules are configured based on domain names or allowed IPs:
+
+```typescript
+import { PortProxy } from '@push.rocks/smartproxy';
+
+const myComplexPortProxy = new PortProxy({
+  fromPort: 6000,
+  toPort: 3000,
+  domains: [
+    {
+      domain: 'api.example.com',
+      allowedIPs: ['192.168.0.*', '127.0.0.1'],
+      targetIP: '192.168.1.100'
+    }
+    // Define more domain-specific rules if needed
+  ],
+  sniEnabled: true,  // if SNI (Server Name Indication) is desired
+  defaultAllowedIPs: ['*']);
+});
+
+// Start listening for complex routing requests
+await myComplexPortProxy.start();
+```
+
+### WebSocket Support and Load Handling
+
+With the advent of real-time applications, efficient WebSocket handling in proxies is crucial. Smartproxy integrates WebSocket support seamlessly, enabling it to proxy WebSocket traffic while maintaining security and performance:
+
+```typescript
+import { NetworkProxy } from '@push.rocks/smartproxy';
+
+const wsProxy = new NetworkProxy({ port: 443 });
+
+// Assume reverse proxy configurations with WebSocket intentions
+const wsProxyConfigs = [
+  {
+    destinationIp: '127.0.0.1',
+    destinationPort: '8080',
+    hostName: 'socket.example.com',
+    // Add further options such as keys for SSL if needed
+  }
+];
+
+// Start the network proxy with WebSocket capabilities
+await wsProxy.start();
+await wsProxy.updateProxyConfigs(wsProxyConfigs);
+
+// Ensure WebSocket connections remain alive
+wsProxy.heartbeatInterval = setInterval(() => {
+  // logic for keeping connections alive and healthy
+}, 60000); // Every 60 seconds
+
+// Gracefully handle server or connection errors to maintain uptime
+wsProxy.httpsServer.on('error', (error) => console.log('Server Error:', error));
+```
+
+### Comprehensive Routing and Advanced Features
+
+Smartproxy supports dynamic and customizable request routing based on the incoming request's destination. This feature enables extensive use-case scenarios, from simple API endpoint redirection to elaborate B2B service integrations:
+
+```typescript
+import { NetworkProxy } from '@push.rocks/smartproxy';
+
+const dynamicRoutingProxy = new NetworkProxy({ port: 8443 });
+dynamicRoutingProxy.router.setNewProxyConfigs([
+  {
+    destinationIp: '192.168.1.150',
+    destinationPort: '80',
+    hostName: 'dynamic.example.com',
+    authentication: {
+      type: 'Basic',
+      user: 'admin',
+      pass: 'password123'
+    }
+  }
+]);
+
+await dynamicRoutingProxy.start();
+```
+
+For those dealing with high volume or regulatory needs, the integration of tools like `iptables` allows broad control over network traffic:
+
+```typescript
+import { IPTablesProxy } from '@push.rocks/smartproxy';
+
+// Setting up iptables for advanced network management
+const ipTablesProxy = new IPTablesProxy({
+  fromPort: 8081,
+  toPort: 8080,
+  deleteOnExit: true // clean rules upon server shutdown
+});
+
+// Begin routing with IPTables
+await ipTablesProxy.start();
+```
+
+### Combining with HTTP and HTTPS Credentials
+
+When undertaking proxy configurations, handling sensitive data like SSL certificates and keys securely is imperative:
+
+```typescript
+import { loadDefaultCertificates } from '@push.rocks/smartproxy';
+
+try {
+  const { privateKey, publicKey } = loadDefaultCertificates(); // adjust path as needed
+  console.log('Certificates loaded.');
+  // Use these certificates in your SSL-based configurations
+} catch (error) {
+  console.error('Cannot load certificates:', error);
+}
+```
+
+### Testing and Validation
+
+Given these powerful capabilities, rigorous testing of configurations and functionality using frameworks like `tap` can ensure high-quality and reliable proxy configurations. Smartproxy integrates with Typescript test setups:
+
+```typescript
+import { expect, tap } from '@push.rocks/tapbundle';
+import { NetworkProxy } from '@push.rocks/smartproxy';
+
+tap.test('proxied request should return status 200', async () => {
+  // Your test logic here
+});
+
+tap.start();
+```
+
+In summary, `@push.rocks/smartproxy` offers a plethora of solutions tailored to both common and sophisticated proxying needs. Whether you're seeking straightforward port forwarding, secure SSL redirection, WebSocket management, or robust network routing controls, smartproxy provides the right tools for efficient and effective proxy operations.
