Jeena	33ae576b25	Implement rate limiting with 41 responses and comprehensive logging ... - Add concurrent connection handling with tokio::spawn for proper rate limiting - Send '41 Server unavailable' responses instead of dropping connections - Move request logger initialization earlier to enable rate limiting logs - Add logging for rate limited requests: 'Concurrent request limit exceeded' - Fix clippy warnings: needless borrows and match simplification - Update test script analysis to expect 41 responses for rate limiting	2026-01-16 06:00:18 +00:00
Jeena	1500057a92	Add max concurrent requests to startup info ... Display the configured max_concurrent_requests value in the server startup information, consistent with other configuration values like log level, host, port, etc.	2026-01-16 02:42:18 +00:00
Jeena	0468781a69	Add configurable global concurrent request limiting ... - Add max_concurrent_requests config option (default: 1000) - Implement global AtomicUsize counter for concurrent request tracking - Return status 41 'Server unavailable' when limit exceeded - Proper counter management with decrements on all exit paths - Add comprehensive config validation (1-1,000,000 range) - Update documentation with rate limiting details - Add unit tests for config parsing - Thread-safe implementation using Ordering::Relaxed This provides effective DDoS protection by limiting concurrent connections to prevent server overload while maintaining configurability for different deployment scenarios.	2026-01-16 02:26:59 +00:00
