Please have a look to those documentation:

• https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Status/304
• https://en.wikipedia.org/wiki/URL_redirection
• https://datatracker.ietf.org/doc/html/rfc2068#section-10.3.5
• https://www.rfc-editor.org/rfc/rfc9110.html#section-15.4.5

Even if specified headers are not implemented in app, behaviour is normal since 304 answer is not a 'real redirection' and isn't supposed to have an enclosed body:

"GET /304 HTTP/1.0"
"User-Agent: Jakarta Commons-HttpClient/3.1"
"Host: localhost:8080"
""
"HTTP/1.1 304 Not Modified"
"HTTP/1.1 304 Not Modified"
"Connection: close"
"Date: Thu, 09 Oct 2025 08:59:07 GMT"
"Server: Kestrel"
