```
although URL is valid and wget follows redirect nicely.  Might be that dandi-api does not handle HEAD request correctly while we are trying to get redirect url (so something to file and issue or submit a PR about to dandi-api).  But I do not think in this case we should even try to follow any redirect since all pertinent information is in the URL and we just need to parse it and request metadata record for the asset
