+# HTTP-01 ACME Challenge Fix (v19.3.8)
+
+## Problem Description
+
+In SmartProxy v19.3.7 and earlier, ACME HTTP-01 challenges would fail when port 80 was configured to use HttpProxy via the `useHttpProxy` configuration option. The issue was that non-TLS connections on ports listed in `useHttpProxy` were not being forwarded to HttpProxy, instead being handled as direct connections.
+
+## Root Cause
+
+The bug was located in the `RouteConnectionHandler.handleForwardAction` method in `ts/proxies/smart-proxy/route-connection-handler.ts`. The method only forwarded connections to HttpProxy if they had TLS settings with mode 'terminate' or 'terminate-and-reencrypt'. Non-TLS connections (like HTTP on port 80) were always handled as direct connections, regardless of the `useHttpProxy` configuration.
+
+## Solution
+
+The fix adds a check for non-TLS connections on ports listed in the `useHttpProxy` array:
+
+```typescript
+// No TLS settings - check if this port should use HttpProxy
+const isHttpProxyPort = this.settings.useHttpProxy?.includes(record.localPort);
+
+if (isHttpProxyPort && this.httpProxyBridge.getHttpProxy()) {
+  // Forward non-TLS connections to HttpProxy if configured
+  if (this.settings.enableDetailedLogging) {
+    console.log(
+      `[${connectionId}] Using HttpProxy for non-TLS connection on port ${record.localPort}`
+    );
+  }
+  
+  this.httpProxyBridge.forwardToHttpProxy(
+    connectionId,
+    socket,
+    record,
+    initialChunk,
+    this.settings.httpProxyPort || 8443,
+    (reason) => this.connectionManager.initiateCleanupOnce(record, reason)
+  );
+  return;
+}
+```
+
+## Configuration
+
+To enable ACME HTTP-01 challenges on port 80 with HttpProxy:
+
+```typescript
+const proxy = new SmartProxy({
+  useHttpProxy: [80], // Must include port 80 for HTTP-01 challenges
+  httpProxyPort: 8443, // Default HttpProxy port
+  acme: {
+    email: 'ssl@example.com',
+    port: 80, // ACME challenge port
+    useProduction: false
+  },
+  routes: [
+    {
+      name: 'https-route',
+      match: {
+        ports: 443,
+        domains: 'example.com'
+      },
+      action: {
+        type: 'forward',
+        target: { host: 'localhost', port: 8080 },
+        tls: {
+          mode: 'terminate',
+          certificate: 'auto',
+          acme: {
+            email: 'ssl@example.com',
+            useProduction: false
+          }
+        }
+      }
+    }
+  ]
+});
+```
+
+## Testing
+
+The fix is verified by unit tests in `test/test.http-fix-unit.ts`:
+
+1. **Test 1**: Verifies that non-TLS connections on ports in `useHttpProxy` are forwarded to HttpProxy
+2. **Test 2**: Confirms that ports not in `useHttpProxy` still use direct connections
+3. **Test 3**: Validates that ACME HTTP-01 challenges on port 80 work correctly with HttpProxy
+
+## Impact
+
+This fix enables proper ACME HTTP-01 challenge handling when:
+1. Port 80 is configured in the `useHttpProxy` array
+2. An ACME challenge route is configured to use HTTP-01 validation
+3. Certificate provisioning with `certificate: 'auto'` is used
+
+Without this fix, HTTP-01 challenges would fail because the challenge requests would not reach the ACME handler in HttpProxy.
+
+## Migration Guide
+
+If you were experiencing ACME HTTP-01 challenge failures:
+
+1. Update to SmartProxy v19.3.8 or later
+2. Ensure port 80 is included in your `useHttpProxy` configuration
+3. Verify your ACME configuration includes the correct email and port settings
+4. Test certificate renewal with staging ACME first (`useProduction: false`)

+## HTTP-01 ACME Challenge Fix (v19.3.8)
+
+### Issue
+Non-TLS connections on ports configured in `useHttpProxy` were not being forwarded to HttpProxy. This caused ACME HTTP-01 challenges to fail when the ACME port (usually 80) was included in `useHttpProxy`.
+
+### Root Cause
+In the `RouteConnectionHandler.handleForwardAction` method, only connections with TLS settings (mode: 'terminate' or 'terminate-and-reencrypt') were being forwarded to HttpProxy. Non-TLS connections were always handled as direct connections, even when the port was configured for HttpProxy.
+
+### Solution
+Added a check for non-TLS connections on ports listed in `useHttpProxy`:
+```typescript
+// No TLS settings - check if this port should use HttpProxy
+const isHttpProxyPort = this.settings.useHttpProxy?.includes(record.localPort);
+
+if (isHttpProxyPort && this.httpProxyBridge.getHttpProxy()) {
+  // Forward non-TLS connections to HttpProxy if configured
+  this.httpProxyBridge.forwardToHttpProxy(/*...*/);
+  return;
+}
+```
+
+### Test Coverage
+- `test/test.http-fix-unit.ts` - Unit tests verifying the fix
+- Tests confirm that non-TLS connections on HttpProxy ports are properly forwarded
+- Tests verify that non-HttpProxy ports still use direct connections
+
+### Configuration Example
+```typescript
+const proxy = new SmartProxy({
+  useHttpProxy: [80], // Enable HttpProxy for port 80
+  httpProxyPort: 8443,
+  acme: {

-   - Renamed NetworkProxy references to HttpProxy
-   - Renamed test files to match new naming
-   - Updated imports and references throughout tests
-   - Fixed certificate manager method names
-
-2. **Update documentation**
-   - Updated README to reflect HttpProxy naming
-   - Updated architecture descriptions
-   - Updated usage examples
-   - Fixed all API documentation references
-
-## Migration Steps
-
-1. Create feature branch: `refactor/http-proxy-consolidation`
-2. Phase 1: Rename NetworkProxy (1 day)
-3. Phase 2: Extract HTTP logic (2 days)
-4. Phase 3: Simplify SmartProxy (1 day)
-5. Phase 4: Consolidate utilities (1 day)
-6. Phase 5: Update tests/docs (1 day)
-7. Integration testing (1 day)
-8. Code review and merge
-
-## Benefits
-
-1. **Clear Separation**: HTTP/HTTPS handling is clearly separated from TCP routing
-2. **Better Naming**: HttpProxy clearly indicates its purpose
-3. **No Duplication**: HTTP parsing logic exists in one place
-4. **Maintainability**: Easier to modify HTTP handling without affecting routing
-5. **Testability**: Each component has a single responsibility
-6. **Performance**: Optimized paths for different traffic types
-
-## Future Enhancements
-
-After this refactoring, we can more easily add:
-
-1. HTTP/3 (QUIC) support in HttpProxy
-2. Advanced HTTP features (compression, caching)
-3. HTTP middleware system
-4. Protocol-specific optimizations
-5. Better HTTP/2 multiplexing
-
-## Breaking Changes from v18 to v19
-
-1. `NetworkProxy` class renamed to `HttpProxy`
-2. Import paths change from `network-proxy` to `http-proxy`
-3. Global ACME configuration now available at the top level
-4. Certificate management unified under SmartCertManager
-
-## Future Enhancements
