Well, the exact design would be up to you to decide of course.

That too is up to you and the protocol/server you're talking to.

I would expect that most streaming services would rather first stop the
current download/stream, and then making a subsequent request to ask for the
stream to start at a different place.

But all this is not about HTTP, nor about libcurl but about what your
application and the server you communicate with support.

I don't see how it is a libcurl problem.

Download is a stream, there's no difference to libcurl.
