Ah ok, I'm not entirely surprised. It could be a number of things,
but tbh I suspect that it's going to be difficult to get this to work.
Why don't you do a head request before the get? That way you would get just the headers and could prompt the user and possibly fork before beginning the download?
I suspect this is the cleanest design without getting into multi-threading.
Although it adds an extra round-trip, it'll probably not be that noticeable (if at all).
