Then I'd suggest:

  curl --range "0-2047" [URL] | head -c 2048

... since that would make range-accepting servers only provide the amount
you're interested in, and only the ones that aren't acknowledging Range: will
provide more and let head cut it. Mostly since this is possible to do with a
non-patched curl.

The 2353 vs 4111 will of course vary greatly between operating systems,
networks and servers.
