# Summary [NIFI-3869](https://issues.apache.org/jira/browse/NIFI-3869) Adds configurable support the HTTP/2 protocol in the `ListenHTTP` and `HandleHttpRequest` Processors. The implementation includes a new `nifi-jetty-configuration` module under `nifi-commons` containing a reusable `ServerConnectorFactory` and standard implementation. The configuration module includes a custom Application Layer Protocol Negotiation (ALPN) Processor that supports Java 8 Update 251 and later, which aligns with the current minimum required Java version for NiFi. The Jetty `http2-server` and `jetty-alpn-server` libraries are now included in the `nifi-jetty-bundle` along with all other required Jetty libraries. Both `ListenHTTP` and `HandleHttpRequest` include a new `HTTP Protocols` property that depends on the `SSL Context Service` property. Enabling HTTP/2 requires enabling TLS, and both components default to HTTP/1.1 for both standard and TLS configurations in order to avoid unexpected changes when upgrading. The HTTP/2 protocol supports negotiating support based on client requests using ALPN, but maintaining HTTP/1.1 as the default property setting allows administrators to enable HTTP/2 support if desired. The `HTTP Protocols` property supports the following configuration options: - `http/1.1` - `h2 http/1.1` - `h2` The property values correspond to the values defined in [RFC 7540 Section 3.1](https://www.rfc-editor.org/rfc/rfc7540.html#section-3.1) and also align with the approach used for configuring HTTP Protocols in [Apache HTTP Server](https://httpd.apache.org/docs/2.4/mod/core.html#protocols). The value of `h2 http/1.1` enables the server and client to negotiate the supported version, while selecting `h2` or `http/1.1` requires the client to support the selected version. # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [X] [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - [X] Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - [X] Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` ### Pull Request Formatting - [X] Pull Request based on current revision of the `main` branch - [X] Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [X] Build completed using `mvn clean install -P contrib-check` - [X] JDK 8 - [X] JDK 11 - [X] JDK 17 ### Licensing - [ ] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [ ] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [X] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
