    To ensure that data is not corrupted traversing the network, use the Content-MD5 form field. When you use this form field, Amazon S3 checks the object against the provided MD5 value. If they do not match, Amazon S3 returns an error.

    The status code returned to the client upon successful upload if success_action_redirect is not specified.
    Accepts the values 200, 201, or 204 (default).

    To ensure that data is not corrupted traversing the network, use the Content-MD5 form field. When you use this form field, Amazon S3 checks the object against the provided MD5 value. If they do not match, Amazon S3 returns an error. Additionally, you can calculate the MD5 value while posting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value. The ETag only reflects changes to the contents of an object, not its metadata.
