Due to ECS's namespace feature, you must access your bucket's public content by using the URL (namespace).public.ecstestdrive.com/(bucket) or (bucket).(namespace).public.ecstestdrive.com. Currently, only HTTP access is supported. This allows every user to have buckets with the same name but ECS needs to know which namespace you're anonymously accessing. Your namespace is the same as the numeric portion of your Access Key. For example, if your access key is firstname.lastname@example.org, your namespace is 12345.

Unfortunately, at this time, ECS Test Drive does not support CORS. However, we are planning a changeover to start using namespace base URLs in early 2016 that will in turn allow users to test CORS functionality on ECS Test Drive. All currently registered users on ECS Test Drive will be notified appropriately on the progress of this enhancement. Thanks!
