The Ultimate Implementation · Dual-Layer Caching · TTL Jitter · ECS Injection

⚡️

Multi-Tiered Caching

Integrates L1 isolated memory cache with L2 distributed global cache, strictly enforcing TTL constraints to drastically reduce upstream resolution latency.

🛡️

RFC Protocol Compliance

Fully supports ECS with standard-compliant truncation and injection. It ensures precise geolocation routing while protecting privacy, significantly enhancing CDN resolution quality in complex network environments like mainland China.

🌐

Distributed Resilience

Employs collision-resistant FNV-1a hashing and deterministic TTL jitter algorithms to effectively mitigate cache stampedes, sustaining high availability under high concurrency.

🚦

Intelligent Traffic Control

Effectively prevents upstream overload and protocol abuse through request coalescing, payload size validation, and global write rate limiting, ensuring service stability.
