    Setup Nginx HTTP3

    What is HTTP3 ?

    HTTP/3 builds on User Datagram Protocol (UDP), and is already being used by prominent internet companies such as Google and Facebook. If you’re using Chrome and connecting to a Google service, you’re probably already using QUIC.

    The new version of the HTTP protocol benefits from the bare-metal, low-level UDP protocol, and defines many of the new features which were in previous versions of HTTP at the TCP layer. This provides a way of solving constraints within the existing internet infrastructure.

    How to install ?
