Behavior of query to blob service with prefix/delimiter parameters with 2009-09-19 REST API

Question

I'm having trouble properly accessing the blob storage service using raw HTTP requests.  So far, listing raw container contents has worked as expected. Using just a delimiter to simulate directories in the root of the container also works fine. However,
adding a prefix to the query to try to get the contents of "directories" one level down the hierarchy hasn't been successful - all that's returned is the name of the directory I'm trying to list.
I have a container "con" with multiple blobs starting with the string "folder/". The result I'm expecting is a list of Blobs with names in the format "folder/filename" and BlobPrefixes with names like "folder/subfolder/".
Here are the request and response:
GET http://<account>.blob.core.windows.net/con?comp=list&restype=container&prefix=folder/&delimiter=/ HTTP/1.1

I only have this problem if I use API version 2009-09-19 - the same query works correctly with the old version:
GET http://<account>.blob.core.windows.net/con?comp=list&restype=container&prefix=folder/&delimiter=/ HTTP/1.1

I've tried using other clients (Cloud Storage Studio and the CloudBerry Explorer) and they have the same issue - "folders" show up in the container but are themselves empty when they shouldn't be. So, what am I missing here?

Answer 1

My apologies upfront if I misread your explanation above, but you should get the entire listing when using prefix "folder/". For example, I get the below response when using the following request: GET /myfolder?restype=container&comp=list&prefix="0/"&delimiter="/"&timeout=90
HTTP/1.1 with version = 2009-09-19. But looks like you did not get the blobs listed? Is that correct? If yes, can you re-run and provide me with account name and request id (please send it to jharidas at microsoft)? Request and response traces will be
helpful.
Thanks,
jai
