**Thread Safety**: `AtomicLong` for counters, `volatile` for status flags, synchronized blocks, thread-local storage via `CrawlingParameterUtil`

**Resource Management**: `AutoCloseable` throughout, `DeferredFileOutputStream` for large responses, connection pooling, background temp file deletion via `FileUtil.deleteInBackground()`

**Fault Tolerance**: `FaultTolerantClient` wrapper (retry, circuit breaker), `SwitchableHttpClient` for HTTP client fallback
