It's the one that is more complex - with a text-based 'progress-bar' and queueing (for some, probably educational, reason) of requests. Changes: - update the C++ syntax (mem-initializers, range for, etc.) - new-style headers - redirects should not result in creating an empty file. Since we have no UI, and this example is already complex enough, settle for just reporting the redirect and removing the empty file. Task-number: QTBUG-60628 Change-Id: I0b69cd77414ecac7c0bc6b2f8f787befc978de28 Reviewed-by: Edward Welbourne <edward.welbourne@qt.io>
