Hi, thanks for opening this issue. Was trying to implement this, but only made it worse, well, that's what it feels like 😅

I've added support for http://apps.tvgam.es/, but then got blocked after, to some degree, but it worked..

Then tried the others, but those don't return the header, so it took the other route in code, but failed. Fixed that, but then entering a never ending loop because the server doesn't respond like it use to do, if it was a real Amazon S3 API..

http://cds.p6v7v3q9.hwcdn.net/ returns with <NextMarker>FAM/J4/Launcher/Quad/Launcher_QC_2832_Alpha3.apk</NextMarker>, but when I want to retrieve the second page, it just returns the normal results. Because it returns the NextMarker, it looks like the older API, but sadly doesn't respond as it should be.

Example:
https://cds.p6v7v3q9.hwcdn.net/?list-type=2&delimiter=/&prefix=&marker=FAM%2FJ4%2FLauncher%2FQuad%2FLauncher_QC_2832_Alpha3.apk

This SHOULD start with FAM/J4/Launcher/Quad/Launcher_QC_2832_Alpha3.apk, but it just starts with 24XX_JApp/live.png as the starting url would do:
https://cds.p6v7v3q9.hwcdn.net/

So I'm stuck with this, I don't want a never ending loop. If there is a way to make it return the correct results, I would like to support it.

This one does support the new V2 listing and returns a NextContinuationToken:
https://data.openspending.org.s3.amazonaws.com/?list-type=2&delimiter=/&prefix=datasets/&max-keys=10

And also because it is not a 'real' / public bucket as it seems, <Name>cloudstream-d8c2-gcp-content</Name>:
https://cloudstream-d8c2-gcp-content.s3.amazonaws.com/

If anybody has any clue about this, please respond :)

Checked https://github.com/s3fs-fuse/s3fs-fuse and I see that it also support NextContinuationToken, which I will too if I get more info why the https://cds.p6v7v3q9.hwcdn.net/ doesn't work.

I've also asked @qoomon who might have more experience with it. Lets hope there is more info.
