## ACL
For now there are some limitations:
* [Bucket policy](https://docs.aws.amazon.com/AmazonS3/latest/userguide/bucket-policies.html) supports only one `Principal` per `Statement`.
Principal must be `"AWS": "*"` (to refer all users) or `"CanonicalUser": "0313b1ac3a8076e155a7e797b24f0b650cccad5941ea59d7cfd51a024a8b2a06bf"` (hex encoded public key of desired user).
* Resource in bucket policy is an array. Each item MUST contain bucket name, CAN contain object name (wildcards are not supported):
```json
{
"Statement": [
{
"Resource": [
"arn:aws:s3:::bucket",
"arn:aws:s3:::bucket/some/object"
]
}
]
}
```
* AWS conditions and wildcard are not supported in [resources](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-arn-format.html)
* Only `CanonicalUser` (with hex encoded public key) and `All Users Group` are supported in [ACL](https://docs.aws.amazon.com/AmazonS3/latest/userguide/acl-overview.html)

## Multipart
CompleteMultipartUpload operations may take long time to complete. Gateway
sends whitespace characters to keep connection with the client alive. In this
case, gateway is unable to set proper HTTP headers like `X-Amz-Version-Id`.
