# Summary [NIFI-15953](https://issues.apache.org/jira/browse/NIFI-15953) Updates the Administrator's Guide documentation for the `nifi.web.proxy.host` header and implements additional validation for proxy host header values based on the configured property. The documentation clarifies the behavior of `Host` header validation when running with HTTPS enabled, describing TLS Server Name Indication and DNS Subject Alternative Name requirements for server certificates. Property description details also describe expected behavior for reverse proxy servers that provide the `X-ProxyHost` or `X-Forwarded-Host` header values. The additional Proxy Header Validator follows the same pattern as the Host Port Validator, returning an HTTP 421 Misdirected Request when receiving an invalid host header string. The implementation and documentation maintain existing requirements that enforce validation when the application is running with HTTPS enabled. Unit test updates exercise the configured Proxy Header Validator and assert expected HTTP response status codes. # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` - Pull request contains [commits signed](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) with a registered key indicating `Verified` status ### Pull Request Formatting - Pull Request based on current revision of the `main` branch - 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 `./mvnw clean install -P contrib-check` - [X] JDK 21 - [X] JDK 25 ### 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.
