- Introduced a new error handling system with custom error types for better context and clarity in error reporting. - Implemented URL validation to prevent invalid requests and enhance security. - Updated cache key generation functions to return errors, improving robustness in handling invalid inputs. - Added comprehensive metrics tracking for requests, cache hits, misses, and performance metrics, allowing for better monitoring and analysis of the caching system. - Enhanced logging to include detailed metrics and error information for improved debugging and operational insights.
