"""
Once your client has connected to the server and sent the HTTP
request, the read timeout is the number of seconds the client will
wait for the server to send a response. (Specifically, it's the number
of seconds that the client will wait between bytes sent from the
server. In 99.9% of cases, this is the time before the server sends
the first byte).
"""
"Between bytes" implies that you could have a long request, as long as
there's a keep-alive transmission every few seconds.
