Nope, it is - unless you think "loading html pages from a remote web server" is also not static.

The point is there's no computation going on on the server, behind the scenes; your browser is doing all the work of knowing what to fetch, NOT the remote end, with the magic of range requests.

That's what's so brilliant about this. The database query happens on the client, not on the server. The server side is entirely static hosting.
