setContentRange
fun setContentRange(start: <Error class: unknown class>, end: <Error class: unknown class>, totalLength: <Error class: unknown class>)

class@Server has built-in handling for range requests, and you do not normally need to call this function youself. See method@MessageHeaders.get_ranges for more details.
Parameters
start
the start of the range
end
the end of the range
totalLength
the total length of the resource, or -1 if unknown
