HTTP/2 and HTTP/3

Modern HTTP protocol versions offering performance improvements over HTTP/1.1.

HTTP/2 introduced multiplexing, header compression and server push; HTTP/3 (based on QUIC) further reduces connection latency and handles network changes gracefully. Both improve real-world performance for image-heavy and resource-rich sites. Wix supports HTTP/2 and HTTP/3 across the global CDN, contributing to consistent fast delivery.
