> If you upload a multipart blob named "foo" and then upload a non-multipart blob named "foo.bar" to the same container then when you get the contents of "foo" they will include the contents of "foo.bar".
> This happens because CommonSwiftAsyncClient uses the blob's name as the value for the X-Object-Manifest header, and swift includes all blobs whose names start with this value when responding to a GET on the multipart blob.
> http://docs.openstack.org/trunk/openstack-object-storage/admin/content/direct-api-management-of-large-objects.html and http://www.rackspace.com/blog/rackspace-cloud-files-now-supporting-extremely-large-file-sizes/ append a / to the end of the X-Object-Manifest header which avoids this issue in the common case (it can still happen if a blob with / in the name is uploaded, but this is likely to be uncommon because / does not commonly appear in filenames as it is the UNIX path separator character).
