Define secondary throttle and/or set the given upload or download rate. Attach to a download with the d.set_throttle_name=name command
or switch throttles with Ctrl-T. Download must be stopped when changing throttles. Note that secondary throttles only work if the
global upload/download is throttled. Setting a download to use the <emphasis>NULL</emphasis> throttle makes the download unthrottled
even when there is a global throttle. Note that this special case bypasses the global throttle entirely, and as such its rate and
transfer amounts are not included in the global statistics.
