Comment by S3ForMe

We are using our own self-written software to implement S3 protocol. We do not support all enterprise-features like extended ACL, regions, encryption, this makes our software much simpler and easier to develop. You can find basic documentation here https://my.s3for.me/client/docs/index, all the rest documentation can be found at Amazon S3 documentation site, it is basically the same with small differences. Edit: can't post comments for some time (You're submitting too fast...), will reply later.
