Thank you for the update, this looks good to me. I'll let Michael (and Daniel) have a chance to review the updated version.

On a general note, since you are contributing to the `HttpServer` area, I would also recommend that you run `tier2` tests locally. The GitHub actions job for the JDK only runs tier1 and that tier doesn't cover the networking area.
