You will have to play around with the quick_abort_* and range_offset
directives to force-download a while file when a range is requested.
That way the file gets cached and later requests get the cached version.

This may need to be combined with maxconn ACL to limit the number of
simultaneous connections from each client to prevent bandwidth waste.
