- Removed the forwarding namespace export from main index
- Removed TForwardingType and all forwarding handlers
- Consolidated route helper functions into route-helpers.ts
- All functionality is now available through the route-based system
- Users must migrate from forwarding.* imports to direct route helper imports

-# SmartProxy Implementation Plan
+# SmartProxy Enhanced Routing Plan
 
-## Feature: Custom Certificate Provision Function
+## Goal
+Implement enhanced routing structure with multiple targets per route, sub-matching capabilities, and target-specific overrides to enable more elegant and DRY configurations.
 
-### Summary
+## Key Changes
-This plan implements the `certProvisionFunction` feature that allows users to provide their own certificate generation logic. The function can either return a custom certificate or delegate back to Let's Encrypt by returning 'http01'.
 
-### Key Changes
+### 1. Update Route Target Interface
-1. Add `certProvisionFunction` support to CertificateManager
+- Add `match` property to `IRouteTarget` for sub-matching within routes
-2. Modify `provisionAcmeCertificate()` to check custom function first
+- Add target-specific override properties (tls, websocket, loadBalancing, etc.)
-3. Add certificate expiry parsing for custom certificates
+- Add priority field for controlling match order
-4. Support both initial provisioning and renewal
-5. Add fallback configuration option
 
-### Overview
+### 2. Update Route Action Interface
-Implement the `certProvisionFunction` callback that's defined in the interface but currently not implemented. This will allow users to provide custom certificate generation logic while maintaining backward compatibility with the existing Let's Encrypt integration.
+- Remove singular `target` property
+- Use only `targets` array (single target = array with one element)
+- Maintain backwards compatibility during migration
 
-### Requirements
+### 3. Implementation Steps
-1. The function should be called for any new certificate provisioning or renewal
-2. Must support returning custom certificates or falling back to Let's Encrypt
-3. Should integrate seamlessly with the existing certificate lifecycle
-4. Must maintain backward compatibility
 
-### Implementation Steps
+#### Phase 1: Type Updates
+- [x] Update `IRouteTarget` interface in `route-types.ts`
+  - Add `match?: ITargetMatch` property
+  - Add override properties (tls, websocket, etc.)
+  - Add `priority?: number` field
+- [x] Create `ITargetMatch` interface for sub-matching criteria
+- [x] Update `IRouteAction` to use only `targets: IRouteTarget[]`
 
-#### 1. Update Certificate Manager to Support Custom Provision Function
+#### Phase 2: Route Resolution Logic
-**File**: `ts/proxies/smart-proxy/certificate-manager.ts`
+- [x] Update route matching logic to handle multiple targets
+- [x] Implement target sub-matching algorithm:
+  1. Sort targets by priority (highest first)
+  2. For each target with a match property, check if request matches
+  3. Use first matching target, or fallback to target without match
+- [x] Ensure target-specific settings override route-level settings
 
-- [ ] Add `certProvisionFunction` property to CertificateManager class
+#### Phase 3: Code Migration
-- [ ] Pass the function from SmartProxy options during initialization
+- [x] Find all occurrences of `action.target` and update to use `action.targets`
-- [ ] Modify `provisionCertificate()` method to check for custom function first
+- [x] Update route helpers and utilities
+- [x] Update certificate manager to handle multiple targets
+- [x] Update connection handlers
 
-#### 2. Implement Custom Certificate Provisioning Logic
+#### Phase 4: Testing
-**Location**: Modify `provisionAcmeCertificate()` method
+- [x] Update existing tests to use new format
+- [ ] Add tests for multi-target scenarios
+- [ ] Add tests for sub-matching logic
+- [ ] Add tests for setting overrides
 
+#### Phase 5: Documentation
+- [ ] Update type documentation
+- [ ] Add examples of new routing patterns
+- [ ] Document migration path for existing configs
+
+## Example Configurations
+
+### Before (Current)
 ```typescript
-private async provisionAcmeCertificate(
+// Need separate routes for different ports/paths
-  route: IRouteConfig, 
+[
-  domains: string[]
+  {
-): Promise<void> {
+    match: { domains: ['api.example.com'], ports: [80] },
-  const primaryDomain = domains[0];
+    action: {
-  const routeName = route.name || primaryDomain;
+      type: 'forward',
-  
+      target: { host: 'backend', port: 8080 },
-  // Check for custom provision function first
+      tls: { mode: 'terminate' }
-  if (this.certProvisionFunction) {
-    try {
-      logger.log('info', `Attempting custom certificate provision for ${primaryDomain}`, { domain: primaryDomain });
-      const result = await this.certProvisionFunction(primaryDomain);
-      
-      if (result === 'http01') {
-        logger.log('info', `Custom function returned 'http01', falling back to Let's Encrypt for ${primaryDomain}`);
-        // Continue with existing ACME logic below
-      } else {
-        // Use custom certificate
-        const customCert = result as plugins.tsclass.network.ICert;
-        
-        // Convert to internal certificate format
-        const certData: ICertificateData = {
-          cert: customCert.cert,
-          key: customCert.key,
-          ca: customCert.ca || '',
-          issueDate: new Date(),
-          expiryDate: this.extractExpiryDate(customCert.cert)
-        };
-        
-        // Store and apply certificate
-        await this.certStore.saveCertificate(routeName, certData);
-        await this.applyCertificate(primaryDomain, certData);
-        this.updateCertStatus(routeName, 'valid', 'custom', certData);
-        
-        logger.log('info', `Custom certificate applied for ${primaryDomain}`, { 
-          domain: primaryDomain,
-          expiryDate: certData.expiryDate
-        });
-        return;
     }
-    } catch (error) {
-      logger.log('error', `Custom cert provision failed for ${primaryDomain}: ${error.message}`, {
-        domain: primaryDomain,
-        error: error.message
-      });
-      // Configuration option to control fallback behavior
-      if (this.smartProxy.settings.certProvisionFallbackToAcme !== false) {
-        logger.log('info', `Falling back to Let's Encrypt for ${primaryDomain}`);
-      } else {
-        throw error;
-      }
-    }
-  }
-  
-  // Existing Let's Encrypt logic continues here...
-  if (!this.smartAcme) {
-    throw new Error('SmartAcme not initialized...');
-  }
-  // ... rest of existing code
-}
-```
-
-#### 3. Add Helper Method for Certificate Expiry Extraction
-**New method**: `extractExpiryDate()`
-
-- [ ] Parse PEM certificate to extract expiry date
-- [ ] Use existing certificate parsing utilities
-- [ ] Handle parse errors gracefully
-
-```typescript
-private extractExpiryDate(certPem: string): Date {
-  try {
-    // Use forge or similar library to parse certificate
-    const cert = forge.pki.certificateFromPem(certPem);
-    return cert.validity.notAfter;
-  } catch (error) {
-    // Default to 90 days if parsing fails
-    return new Date(Date.now() + 90 * 24 * 60 * 60 * 1000);
-  }
-}
-```
-
-#### 4. Update SmartProxy Initialization
-**File**: `ts/proxies/smart-proxy/index.ts`
-
-- [ ] Pass `certProvisionFunction` from options to CertificateManager
-- [ ] Validate function if provided
-
-#### 5. Add Type Safety and Validation
-**Tasks**:
-- [ ] Validate returned certificate has required fields (cert, key, ca)
-- [ ] Check certificate validity dates
-- [ ] Ensure certificate matches requested domain
-
-#### 6. Update Certificate Renewal Logic
-**Location**: `checkAndRenewCertificates()`
-
-- [ ] Ensure renewal checks work for both ACME and custom certificates
-- [ ] Custom certificates should go through the same `provisionAcmeCertificate()` path
-- [ ] The existing renewal logic already calls `provisionCertificate()` which will use our modified flow
-
-```typescript
-// No changes needed here - the existing renewal logic will automatically
-// use the custom provision function when calling provisionCertificate()
-private async checkAndRenewCertificates(): Promise<void> {
-  // Existing code already handles this correctly
-  for (const route of routes) {
-    if (this.shouldRenewCertificate(cert, renewThreshold)) {
-      // This will call provisionCertificate -> provisionAcmeCertificate
-      // which now includes our custom function check
-      await this.provisionCertificate(route);
-    }
-  }
-}
-```
-
-#### 7. Add Integration Tests
-**File**: `test/test.certificate-provision.ts`
-
-- [ ] Test custom certificate provision
-- [ ] Test fallback to Let's Encrypt ('http01' return)
-- [ ] Test error handling
-- [ ] Test renewal with custom function
-
-#### 8. Update Documentation
-**Files**: 
-- [ ] Update interface documentation
-- [ ] Add examples to README
-- [ ] Document ICert structure requirements
-
-### API Design
-
-```typescript
-// Example usage
-const proxy = new SmartProxy({
-  certProvisionFunction: async (domain: string) => {
-    // Option 1: Return custom certificate
-    const customCert = await myCustomCA.generateCert(domain);
-    return {
-      cert: customCert.certificate,
-      key: customCert.privateKey,
-      ca: customCert.chain
-    };
-    
-    // Option 2: Use Let's Encrypt for certain domains
-    if (domain.endsWith('.internal')) {
-      return customCert;
-    }
-    return 'http01'; // Fallback to Let's Encrypt
   },
-  certProvisionFallbackToAcme: true, // Default: true
+  {
-  routes: [...]
+    match: { domains: ['api.example.com'], ports: [443] },
-});
+    action: {
+      type: 'forward',
+      target: { host: 'backend', port: 8081 },
+      tls: { mode: 'passthrough' }
+    }
+  }
+]
 ```
 
-### Configuration Options to Add
+### After (Enhanced)
-
 ```typescript
-interface ISmartProxyOptions {
+// Single route with multiple targets
-  // Existing options...
+{
-  
+  match: { domains: ['api.example.com'], ports: [80, 443] },
-  // Custom certificate provision function
+  action: {
-  certProvisionFunction?: (domain: string) => Promise<TSmartProxyCertProvisionObject>;
+    type: 'forward',
-  
+    targets: [
-  // Whether to fallback to ACME if custom provision fails
+      {
-  certProvisionFallbackToAcme?: boolean; // Default: true
+        match: { ports: [80] },
+        host: 'backend',
+        port: 8080,
+        tls: { mode: 'terminate' }
+      },
+      {
+        match: { ports: [443] },
+        host: 'backend',
+        port: 8081,
+        tls: { mode: 'passthrough' }
+      }
+    ]
+  }
 }
 ```
 
-### Error Handling Strategy
+### Advanced Example
+```typescript
+{
+  match: { domains: ['app.example.com'], ports: [443] },
+  action: {
+    type: 'forward',
+    tls: { mode: 'terminate', certificate: 'auto' }, // Route-level default
+    websocket: { enabled: true }, // Route-level default
+    targets: [
+      {
+        match: { path: '/api/v2/*' },
+        host: 'api-v2',
+        port: 8082,
+        priority: 10
+      },
+      {
+        match: { path: '/api/*', headers: { 'X-Version': 'v1' } },
+        host: 'api-v1',
+        port: 8081,
+        priority: 5
+      },
+      {
+        match: { path: '/ws/*' },
+        host: 'websocket-server',
+        port: 8090,
+        websocket: { 
+          enabled: true,
+          rewritePath: '/'  // Strip /ws prefix
+        }
+      },
+      {
+        // Default target (no match property)
+        host: 'web-backend',
+        port: 8080
+      }
+    ]
+  }
+}
+```
 
-1. **Custom Function Errors**:
+## Benefits
-   - Log detailed error with domain context
+1. **DRY Configuration**: No need to duplicate common settings across routes
-   - Option A: Fallback to Let's Encrypt (safer)
+2. **Flexibility**: Different backends for different ports/paths within same domain
-   - Option B: Fail certificate provisioning (stricter)
+3. **Clarity**: All routing for a domain in one place
-   - Make this configurable via option?
+4. **Performance**: Single route lookup instead of multiple
+5. **Backwards Compatible**: Can migrate gradually
 
-2. **Invalid Certificate Returns**:
+## Migration Strategy
-   - Validate certificate structure
+1. Keep support for `target` temporarily with deprecation warning
-   - Check expiry dates
+2. Auto-convert `target` to `targets: [target]` internally
-   - Verify domain match
+3. Update documentation with migration examples
-
+4. Remove `target` support in next major version
-### Testing Plan
-
-1. **Unit Tests**:
-   - Mock certProvisionFunction returns
-   - Test validation logic
-   - Test error scenarios
-
-2. **Integration Tests**:
-   - Real certificate generation
-   - Renewal cycle testing
-   - Mixed custom/Let's Encrypt scenarios
-
-### Backward Compatibility
-
-- If no `certProvisionFunction` provided, behavior unchanged
-- Existing routes with 'auto' certificates continue using Let's Encrypt
-- No breaking changes to existing API
-
-### Future Enhancements
-
-1. **Per-Route Custom Functions**:
-   - Allow different provision functions per route
-   - Override global function at route level
-
-2. **Certificate Events**:
-   - Emit events for custom cert provisioning
-   - Allow monitoring/logging hooks
-
-3. **Async Certificate Updates**:
-   - Support updating certificates outside renewal cycle
-   - Hot-reload certificates without restart
-
-### Implementation Notes
-
-1. **Certificate Status Tracking**:
-   - The `updateCertStatus()` method needs to support a new type: 'custom'
-   - Current types are 'acme' and 'static'
-   - This helps distinguish custom certificates in monitoring/logs
-
-2. **Certificate Store Integration**:
-   - Custom certificates are stored the same way as ACME certificates
-   - They participate in the same renewal cycle
-   - The store handles persistence across restarts
-
-3. **Existing Methods to Reuse**:
-   - `applyCertificate()` - Already handles applying certs to routes
-   - `isCertificateValid()` - Can validate custom certificates
-   - `certStore.saveCertificate()` - Handles storage
-
-### Implementation Priority
-
-1. Core functionality (steps 1-3)
-2. Type safety and validation (step 5)
-3. Renewal support (step 6)
-4. Tests (step 7)
-5. Documentation (step 8)
-
-### Estimated Effort

-- Testing: 2-3 hours
-- Documentation: 1 hour
