Unlike its predecessors which rely on TCP, HTTP/3 is based on [QUIC (Quick UDP Internet Connections) protocol](https://en.wikipedia.org/wiki/QUIC). It brings several benefits that collectively result in reduced latency and improved performance: + + * enabling seamless transition between different network connections, such as switching from Wi-Fi to mobile data. + * eliminating head-of-line blocking, so that a lost packet does not block all streams. + * negotiate TLS versions at the same time as the TLS handshakes, allowing for faster connections. + * providing encryption by default, ensuring that all data transmitted over an HTTP/3 connection is protected and confidential. + * providing zero round-trip time (0-RTT) when communicating with servers that clients already established connections to. + + APISIX currently supports HTTP/3 connections between downstream clients and APISIX. HTTP/3 connections with upstream services is not yet supported. Contributions are welcomed. + + :::caution + + This feature has not been tested at scale and therefore, is not recommended for production use. + + ::: + +## Usage example + +1. To allow for HTTP/3 connections on 9443 port, add the following configurations to the `config.yaml` file: + +```yaml +apisix: + ssl: + listen: + - port: 9443 + enable_http3: true # enable HTTP/3 + ssl_protocols: TLSv1.3 # enable TLSv1.3 +``` + +**note** `enable_http3` requires `TLSv1.3` + +2. Create an SSL object for test.com. + +```shell +curl http://127.0.0.1:9180/apisix/admin/ssls/1 \ +-H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' +{ + "cert" : "'"$(cat t/certs/apisix.crt)"'", + "key": "'"$(cat t/certs/apisix.key)"'", + "snis": ["test.com"] +}' +``` + +3.
