(Much like a phone call: you can't tell how long it is until it's over.) The server *can* include a Content-Length which will tell you how big the file is - or it can just start sending data and close the connection once the whole thing has been transferred, at which point you have no idea how much more data will be sent until you've actually got it! You should be able to set an ACL which will match the Content-Length sent by the server, *if* there is one - but that isn't guaranteed. You should, however, be able to achieve the results you seem to be seeking by using a 20Mb 'burst' in the delay pool: a 15Mb download will not be affected, but a series of 10Mb downloads by a single user will be. Downside: a 30Mb download will start off quickly, then drop to your throttled rate two-thirds of the way through, which isn't quite what I think you were asking for; upside, it'll work fairly reliably, including stopping download managers getting around your throttling by requesting big files in chunks of 10Mb each.
