Content

Intended customers: all customers. Feature description: ALB supports gQUIC and iQUIC. HTTP/3 is an application-layer protocol based on iQUIC. HTTP/3 uses iQUIC to implement multiplexing, congestion control, packet loss detection, and retransmission. HTTP/3 supports faster connection establishment, eliminates head-of-line blocking issues, and supports connection migration in scenarios of client IP address changes. ALB supports gQUIC versions Q46, Q43, and Q39 and Chrome 74 to 81. ALB supports HTTP/3 (h3), which requires Chrome 87 or later.
