Es gibt Situationen, in denen es nützlich ist, dem HTTP-Error benutzerdefinierte Header hinzuzufügen. Zum Beispiel in einigen Sicherheitsszenarien.

When configured, MinIO sends request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.
