crooked translation from stackoverflow, but too lazy to look for the original.
by reference for the case when you need to give the entire response and something to remain counted in the background.
if you need to write and add to the stream in the course of work, then just flushing may not be enough, then the output is finished off for the length of the packet (roughly a thousand gaps).
In general, this is a normal question, a stupidly necessary function, or you know another rake.
