## Outros middlewares

Há muitos outros middlewares ASGI.

Por exemplo:

		trace.Path += typed.Values().Encode()
	case *NoPayload, *Bytes:

	case string:
		trace.Path = fmt.Sprintf("%s?%s", trace.Path, typed)
	default:

	trace.HTTP.ReqInfo.Path = trace.Path

"bucketName/objectName" for an object that exists in the bucket, and the value is the JSON-encoded event data about the operation that created/replaced the object in MinIO. When objects are updated or deleted, the corresponding entry in the hash is also updated or deleted.

When the _access_ format is used, MinIO appends events to a list using [RPUSH](https://redis.io/commands/rpush). Each item in the list is a JSON encoded list with two items, where the first item is a timestamp string, and the second...
