NIFI-14115 Set Standard HTTP Headers for Framework Responses

[exceptionfactory]

Summary

NIFI-14115 Adjusts the framework Jetty Server configuration to set standard HTTP headers for all responses, regardless of web application.

The current implementation uses the Spring Security HeaderWriterFilter and applies standard Servlet Filters to configured web applications. This covers both framework REST API and custom extensions, but does not include requests to the root web server path.

The updated implementation replaces the Servlet Filter approach with a HeaderWriterHandler to set the same response headers using a Jetty Handler class. The change introduces a new StandardServerProvider to decouple Jetty Server instance initialization from lifecycle operations. The StandardServerProvider includes decoupled tests for basic operation, including returning expected response headers.

Changes look good. Confirmed all headers previously supported are ported over. Verifying build locally then will merge.

[joewitt]

I tried the build on a different system (linux host) and the build was fine. I suspect what I'm hitting is a local system/security configuration issue. Still reviewing

[exceptionfactory]

Thanks for the feedback @joewitt.

Although I did not have the local build issue, the error points to a potential timing issue with the Jetty Server instance not being ready for the test sends the HTTP request.

To avoid potential timing issues, I simplified the test method to just check that the server start did not fail.

[joewitt]

With timing addressed and header checks changed the test does now pass. Running full clean build to confirm all the things. Have all three commits
