What is HTTP/3? The next-generation web protocol – InfoWorld

HTTP/3 is based on the QUIC (Quick UDP Internet Connections) protocol, which is a transport layer protocol that runs on top of User Datagram Protocol (UDP) instead of Transmission Control Protocol (TCP). This allows for faster and more reliable communication between clients and servers, particularly in situations with high latency or packet loss. Overall, HTTP/3 aims to provide a more responsive and secure web browsing experience for users.
