Amazon CloudFront announces 3 new CloudFront Functions capabilities

Amazon CloudFront now supports three new capabilities for CloudFront Functions: edge location and Regional Edge Cache (REC) metadata, raw query string retrieval, and advanced origin overrides. Developers can now build more sophisticated edge computing logic with greater visibility into CloudFront’s infrastructure and precise, granular control over origin connections. CloudFront Functions allows you to run lightweight JavaScript code at CloudFront edge locations to customize content delivery and implement security policies with sub-millisecond execution times.

Edge location metadata, includes the three-letter airport code of the serving edge location and the expected REC. This enables geo-specific content routing or compliance requirements, such as directing European users to GDPR-compliant origins based on client location. The raw query string capability provides access to the complete, unprocessed query string as received from the viewer, preserving special characters and encoding that may be altered during standard parsing. Advanced origin overrides solve critical challenges for complex application infrastructures by allowing you to customize SSL/TLS handshake parameters, including Server Name Indication (SNI). For example, multi-tenant setups may override SNI where CloudFront connects through CNAME chains that resolve to servers with different certificate domains.

These new CloudFront Functions capabilities are available at no additional charge in all CloudFront edge location. To learn more about CloudFront Functions, see the Amazon CloudFront Developer Guide.
