We discussed this in the slack channel. Probably the best option for you (other
than writing a new plugin) is to use the background_fetch plugin. You will
still need to trigger a download, but you can avoid having to wait for the full
response in the client. So, what you’d do is
curl -H “Range: bytes=0-1” https://www.example.com/some/url/foo.img
And make sure background_fetch is enabled on this remap rule. No matter what
you do, you will have to have something that tells ATS to kick off a download,
and the above is probably as good as any alternative.
