Using “transfer-encoding: chunked”, how much data

问题:

All browsers wait for some content (and sometimes some amount of time, too) before they start rendering a partial http response you have flushed to it across the network - but how much?

回答1:

I did some research on this today with an url endpoint accepting letting me configure chunk sizes and intervals.
