Does NGINX support QUIC?
Our QUIC implementation currently supports BoringSSL and the quictls fork of OpenSSL, which must be compiled with NGINX. We expect the state of QUIC‑enabled SSL/TLS libraries to become clearer during the period when we are merging the nginx-quic development branch into NGINX mainline.
Does NGINX support http3?
Once built, NGINX can be configured to accept incoming HTTP/3 connections by adding the quic and reuseport options to the listen configuration directive. This will enable both HTTP/2 and HTTP/3 on the TCP/443 and UDP/443 ports respectively.
What is new in http3?
HTTP/3 is a new, fast, reliable, and secure protocol across all forms of devices. Instead of TCP, HTTP/3 uses a new protocol, QUIC, developed by Google in 2012. QUIC runs over UDP, the User Datagram Protocol. QUIC provides native multiplexing, and lost packets only impact the streams where data has been lost.
Who uses QUIC protocol?
While the protocol is technically still experimental and in its draft phase, Google already uses it in its Chrome browser. Any connection to a Google server is established via QUIC. As to be expected, everything under Google’s umbrella uses QUIC. YouTube, Blogger, Hangouts – they’re all QUIC-based.
What port does QUIC use?
UDP port 443
QUIC uses server UDP port 443 instead of TCP 443. QUIC has no head-of-line blocking.
Does Safari support http3?
It has been supported by Google Chrome (including Chrome for Android, and Microsoft Edge, which is based on it) since April 2020 and by Mozilla Firefox since May 2021. Safari 14 (on macOS Big Sur and iOS 14) has also implemented the protocol but support is hidden behind a feature flag.
Is HTTP 3 Ready?
HTTP/3 is the latest version of HTTP. Although not officially released yet, HTTP/3 is already extensively deployed. Earlier versions of HTTP were released in 2015 (HTTP/2), 1999 (HTTP/1.1), 1997 (HTTP/1.0), and 1989 (HTTP/0.9).
Should QUIC be blocked?
At the time of writing, the advice from most firewall vendors is to block QUIC until support is officially added to their products. This recommended method will vary from firewall to firewall. Some firewalls allow QUIC by default while others block it by default, but all firewalls are able to allow or block it.
Is QUIC reliable?
QUIC is a connection-oriented transport protocol that provides a reliable data stream delivery service over UDP. This is similar to an independent TCP connection, but with drastically reduced connection setup latency (0-RTT).
Is Nginx old?
The software was created by Igor Sysoev and publicly released in 2004. Nginx is free and open-source software, released under the terms of the 2-clause BSD license….Nginx.

Does Nginx support HTTP/3 and QUIC?
Today we announce the initial release of the official QUIC and HTTP/3 implementation for NGINX, the http_v3_module. This is a technology preview and must be considered experimental – it is not for production use.
Does QUIC support SSL/TLS?
QUIC supports the TLS 1.3 standard, but the TLS software implementation must also support QUIC’s interfaces. NGINX typically uses OpenSSL as an external dependency which means we can take advantage of the SSL/TLS libraries that ship with the operating system in our official NGINX Open Source packages and in NGINX Plus.
When will the nginx code merge be complete?
Our current target for completing the code merge into the NGINX mainline branch is the end of 2021, after which it will be a full part of the NGINX mainline branch and NGINX Plus in subsequent releases. Our next focus will be to optimize performance.
Why does ngnginx use multiple worker processes?
NGINX uses multiple worker processes which enables highly scalable performance across multiple CPU cores. For maximum efficiency, we like to handle each connection with the same worker process. QUIC makes this challenging, as a connection is not tied to the client’s IP address, and the Linux kernel doesn’t provide UDP port-to-process affinity.
