Deleting of DLO object using CURL does not delete the segments. It does deletion of Manifest file alone. Is there any header required for DLO object deletion.

[Janie Richling (jrichli)]

You must use the query parameter ?multipart-manifest=delete as described in : https://docs.openstack.org/developer/swift/overview_large_objects.html#deleting-a-large-object

Only works for SLO, not DLO:

Seems like a legit feature request to me.
