isRestoreInProgress

Specifies whether the object is currently being restored. If the object restoration is in progress, the header returns the value TRUE. For example:

x-amz-optional-object-attributes: IsRestoreInProgress="true"

If the object restoration has completed, the header returns the value FALSE. For example:

x-amz-optional-object-attributes: IsRestoreInProgress="false", RestoreExpiryDate="2012-12-21T00:00:00.000Z"

If the object hasn't been restored, there is no header response.
