This article discusses QUIC (Quick UDP Internet Connections), an experimental protocol designed to improve website performance.
QUIC (Quick UDP Internet Connections) is a new, experimental protocol developed by Google. It is designed to improve performance for connection-oriented web applications by using UDP (User Datagram Protocol) instead of the reliable, but slower TCP (Transmission Control Protocol).
QUIC is enabled by default on Turbo accounts, as well as Reseller accounts with Turbo. However, it only works in specific configurations:
To verify that QUIC is active, type the following command at a command prompt. Replace example.com with the domain name of the site you want to check:
curl -I https://example.com
If QUIC is active, the response header contains the alt-svc: quic value, as shown in the following sample header:
HTTP/2 200 x-powered-by: PHP/5.5.38 content-type: text/html date: Mon, 30 Oct 2017 21:39:46 GMT accept-ranges: bytes server: LiteSpeed alt-svc: quic=":443"; ma=2592000; v="35,37,38,39"
