Is kamal-proxy supports range requests?

[AliOsm]

I'm using kamal-proxy in my Rails app and ActiveStorage to store PDF files on the server and serve them using range requests. It was working good with Kamal v1 and Traefik.

I upgraded to Kamal v2 and kamal-proxy yesterday, and the PDF files can't be accessed anymore using the PDFjs library (I can access the files with direct links).

Most likely the issue is about range requests, as PDFjs library uses them to request PDF content based on byte ranges.

So, is kamal-proxy supports range requests? And if no, how to handle this situation? I don't want to move my storage to some cloud provider such as S3 just to have the support for range requests.

If kamal-proxy is supporting range requests, then any thoughts on why this issue happened now?

I fixed it by disabling thruster, and now it is working as expected! Any thoughts on why this happened? Is thruster not forwarding headers correctly?

@AliOsm I'm not sure what the problem would be here, but it's possible you've run into a bug. Any chance you could reproduce the faulty behaviour with a curl command or similar, so we can inspect where it's going wrong?
