curl doesn't *have to*, but it choses to. Keeping the connection alive and
reading a little extra data over it, is usually much faster than tearing down
the connection and creating a new for next request.

If this is done over HTTP/2 (or the coming HTTP/3), the 302 request should be
aborted since we can do that and still maintain the connection but I'm pretty
sure this optimization is still left to implement.

That could be a way to force this behavior you want, sure. But depending on
many conditions, that's not necessarily the faster way.

Yes it is exactly that!
