Once transitioned, GET or HEAD on the object will stream the content from the transitioned tier. In the event that the object needs to be restored temporarily to the local cluster, the AWS [RestoreObject API](https://docs.aws.amazon.com/AmazonS3/latest/API/API_RestoreObject.html) can be utilized.

```
aws s3api restore-object --bucket srcbucket \
--key object \
--restore-request Days=3
```

## API Response

XML response for this API is similar to [AWS STS AssumeRoleWithWebIdentity](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html#API_AssumeRoleWithWebIdentity_ResponseElements)

## Example request and response

Sample request with `curl`:

```sh

      vendor="MinIO Inc <******@****.***>" \
      maintainer="MinIO Inc <******@****.***>" \
      version="${RELEASE}" \
      release="${RELEASE}" \
      summary="MinIO is a High Performance Object Storage, API compatible with Amazon S3 cloud storage service." \

// http://docs.aws.amazon.com/AmazonS3/latest/API/mpUploadUploadPartCopy.html
// for full details. This function treats an empty rangeString as
