Does Minio support MIME type check? For example, when uploading files, users can specify what MIME type should be used for this file. Then Minio analyzes this file and if it is correct (e.g it's valid image) save, if not respond with an error.
Minio supports AWS S3 API which doesn't implement any MIME type based checking. But you can definitely set Content-Type of the object while uploading and it will be preserved by Minio.
