### Metadata
User metadata is stored as x-amz-meta- keys. S3 metadata keys are case insensitive and are always returned in lower case.

| btime | Time of file birth (creation) read from Last-Modified header | RFC 3339 | 2006-01-02T15:04:05.999999999Z07:00 | **Y** |
| cache-control | Cache-Control header | string | no-cache | N |
| content-disposition | Content-Disposition header | string | inline | N |
| content-encoding | Content-Encoding header | string | gzip | N |
| content-language | Content-Language header | string | en-US | N |
