Well, first off, this won't really benefit much from threading. The biggest bottleneck is going to be the speed of your connection to that server. Fetching in parts is likely to actually take longer. It's certainly possible to do what you want, though. What you want is to figure out how big the file is, and then ask the server to download different pieces of it. But you'll need to properly understand what you're doing on the HTTP level. I would advise finding some other way to practice threading.
