# Bug report

# Detailed description

The `AWS.s3.upload()` (official SDK - https://github.com/aws/aws-sdk-js) returns an object with the `Location` key that points to 4566 instead of 4572 (LocalStack S3 port).

## Expected behavior

The `Location` should point to the file on S3.

Example:

```
Location: http://localhost:4572/path/to/bucket.txt
```

## Actual behavior

The `Location` points to the LocalStack entrypoint.

Example:

```
Location: http://localhost:4566/path/to/bucket.txt
```

# Steps to reproduce

- Upload a file to S3 using the official AWS SDK (https://github.com/aws/aws-sdk-js).
- Check out the `Location` property.

## Client code

```javascript
const AWS = require('aws-sdk');
const s3 = new AWS.S3({
  region: 'us-west-1',
  endpoint: 'http://localhost:4566',
  apiVersion: '2006-03-01',
  s3ForcePathStyle: true,
});

(async () => {
  await s3
    .createBucket({ Bucket: 'my-bucket', ACL: 'private' })
    .promise();

  const { Location } = await s3
    .upload({ Key: 'file.txt', Body: 'test', Bucket: 'my-bucket' })
    .promise();

  console.assert(Location === 'http://localhost:4572/my-bucket/file.txt');
})();
```

        result = json.loads(result_str)
        timestamp = result.pop('Timestamp')
        end = timestamp[-5:]
        matcher = re.compile(r'\.[0-9]{3}Z')
        match = matcher.match(end)
