      To avoid flaky test, would you make the resource be served via custom handler so we can ensure server received the request?

      Something similar to
      third_party/blink/web_tests/external/wpt/speculation-rules/prefetch/resources/prefetch.py to put data on server stash and we continuously fetch the stash until it says the server has received the req.
