A try to get a dynamic large object defined with special characters in its X-Object-Manifest header leads to an error. Exact symptoms depend on used frontend/HTTP server. In case of Apache client will get 500 Internal Server Error while nginx returns 502 Bad Gateway:

$ curl -i "$publicURL/DiscImages2/HP%20Pavilion%20dv7-6c95dx%20Recovery%20Disc%20%281%20of%203%29.ISO" -X GET -H "X-Auth-Token: $token"
