Ilya, I have updated our service to support the new header names. DPR and RW. and backwards compatible with CH- headers.

Awesome! One question.. I'm seeing odd results:

igrigorik { /git/http-client-hints } > curl -s http://app.resrc.it/http://www.resrc.it/img/demo/preferred.jpg   -o /dev/null -w "Image bytes: %{size_download}\n"   -H "DPR: 1.0" -H "RW: 100"
Image bytes: 2372

Image bytes: 5240

Am I hitting different servers? I'd expect the filesize to be the same. Same happens when I pass in CH- prefixed headers.

I suspect I know what this is, but will double check and get back to you with something definitive.
