HTTP/3 is Coming https://litespeedtech.com/images/logos/litespeed/litespeed-logo.png 2018-12-18 18:58:16 HTTP/3, the latest version of HTTP is in development. LiteSpeed Technologies has been following up and implementing this new protocol closely. Learn More.

The HTTP/3 Protocol

There is a new version of HTTP in development, and it is to be called HTTP/3.

How are QUIC and HTTP/3 Related?

QUIC was originally a Google effort to improve HTTP/2 by transporting it encrypted over UDP. In 2016, the IETF began working to standardize the protocol. Part of that process involved splitting QUIC into the transport and application protocols. For some time, the application protocol was referred to as HTTP-over-QUIC, but in November of 2018, the IETF announced that HTTP-over-QUIC would be called HTTP/3.

The IETF is still defining what HTTP/3 will look like. There will be several iterations of review and revision before a standard is adopted, and LiteSpeed will continue to be involved every step of the way. Our goal is to be the first to offer a production-ready HTTP/3 server implementation. We did it with SPDY, HTTP/2, and QUIC, and we can do it again!

Our QUIC Implementation

The Internet currently uses a version of the QUIC protocol called "Google QUIC," sometimes abbreviated gQUIC. It started as a Google experiment between the Chrome browser and some of the Google services, in an effort to improve upon HTTP/2. We added support for Google QUIC to our Web Server and ADC products in 2017. At around the same time, Google handed off the protocol to the IETF for standardization..
