Amazon CloudFront Adds Three Functions Enhancements

🔧 Amazon announced three new CloudFront Functions capabilities: edge location and Regional Edge Cache (REC) metadata, raw query string retrieval, and advanced origin overrides. CloudFront Functions runs lightweight JavaScript at edge locations with sub-millisecond execution, and these additions give developers direct visibility into serving edges and expected RECs. The raw query string preserves exact viewer input for precise parsing and compliance, while advanced origin overrides let teams customize SSL/TLS handshake behavior, including SNI, to support multi-tenant and complex backend configurations.
