Hi all, HTTP/3 <https://tools.ietf.org/html/draft-ietf-quic-http-32> is a new protocol based on QUIC (a UDP-based transport protocol) (the QUIC drafts: 1 <https://tools.ietf.org/html/draft-ietf-quic-transport-32>, 2 <https://tools.ietf.org/html/draft-ietf-quic-tls-32>, 3 <https://tools.ietf.org/html/draft-ietf-quic-recovery-32>). The protocol offers:
- Better security (it always uses TLS 1.3 <https://tools.ietf.org/html/rfc8446>), - Request multiplexing without head of line blocking (this is the main limitation of HTTP/2), - Reduces request latency by allowing clients to send a request to an already-visited server with zero connection setup delay, - Uses modern loss detection and recovery mechanisms, - Enable a long-lived connection to migrate across different network paths (currently not available in our implementation). Our implementation is ready for testing. Please try it out: - update Nightly to the newest version - go to about:config and set the "network.http.http3.enabled” to true - a restart is not needed If you find any issue please file a bug under the Core::Networking::Http component (Bugzilla link <https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=Networking%3A+HTTP> ) HTTP/3 will be discovered using AltSvc <https://tools.ietf.org/html/rfc7838> header and frame, therefore Firefox needs to establish a TCP connection and use HTTP/2 or older version first before discovering HTTP/3. Whether the protocol is used can be seen in DevTools (a request protocol version will be HTTP/3) and in about:networking. Some major sites already support HTTP/3, e.g. google, facebook and youtube. Our HTTP/3 library is called neqo (“Nee-ko”). The repo can be found here <https://github.com/mozilla/neqo>. It uses NSS cryptography library. It is written in Rust which helps make it high performance, reduces the lines of source code needed, and lowers the potential for bugs leading to security vulnerabilities. I am looking forward to your feedback, Dragana _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
