What is the meaning of upload events flag in XMLHttpRequest 2?
It forces a preflight request when event listeners are registered.
Its definition is that it "is used in the send() algorithm to determine
whether upload progress events will be dispatched for non same origin
requests." However, it is only set by send, and is only used for passing
in cross-origin request algorithm as force preflight flag.
Correct.
If the current text accurately describes how this flag is supposed to
work, I'd suggest an editorial change that will remove it, and say want
to pass to CORS directly. However, my understanding is that it might in
fact need to prevent dispatching progress events even in case a listener
gets added after invoking CORS. Was that the intention?
It is not needed for that case because events will only be dispatched if a
preflight request was made.
