Headers are also sent as part of the request.

This is documented here:

|header=20-40,MinRate=500 body=20,MinRate=500|

That's tough to say - the directive exists to limit the amount of
resources a single client can take up by being slow. It really depends
per site as some sites may not be particularly bothered by slow clients
or may not have many. It also varies because some sites serve clients
across the world on very slow connections so they may need to tweak the
values to accommodate those users.
