feat(phase-2): implement enhanced redirect tracking with database persistence
🚀 Core Features: - Complete database-persisted redirect tracking system - Enhanced hop analysis with timing, headers, and metadata - Intelligent redirect type detection (301, 302, 307, 308, meta, JS, final) - Automatic redirect loop detection and prevention - Comprehensive status tracking (OK, ERROR, TIMEOUT, LOOP) - Real-time latency measurement per hop 🔧 Technical Implementation: - Production-grade RedirectTrackerService with Prisma integration - Type-safe request/response handling with Zod validation - Advanced rate limiting (200/hour authenticated, 50/hour anonymous) - Flexible authentication (optional auth for broader access) - Robust error handling and structured logging - Comprehensive input validation and sanitization 🌐 API Endpoints: - POST /api/v2/track - Enhanced tracking with database persistence - GET /api/v2/track/:checkId - Retrieve specific check with full hop details - GET /api/v2/projects/:projectId/checks - List project checks with pagination - GET /api/v2/checks/recent - Recent checks for authenticated users - POST /api/v2/track/bulk - Placeholder for Phase 6 bulk processing 📊 Enhanced Data Model: - Persistent check records with complete metadata - Detailed hop tracking with response headers and timing - SSL scheme detection and protocol analysis - Content-Type extraction and analysis - Comprehensive redirect chain preservation 🔒 Security & Performance: - User-based rate limiting for authenticated requests - IP-based rate limiting for anonymous requests - Configurable timeouts and hop limits (1-20 hops, 1-30s timeout) - Request validation prevents malicious input - Structured error responses for API consistency 🔄 Backward Compatibility: - All existing endpoints preserved and functional - Legacy response formats maintained exactly - Zero breaking changes to existing integrations - Enhanced features available only in v2 endpoints 📋 Database Schema: - Checks table for persistent tracking records - Hops table for detailed redirect chain analysis - Foreign key relationships for data integrity - Optimized indexes for performance queries 🧪 Quality Assurance: - Comprehensive test suite for all endpoints - Authentication flow testing - Rate limiting verification - Error handling validation - Legacy compatibility verification Ready for Phase 3: SSL/SEO/Security analysis integration
