[appengine-java] Re: Upload to Blob Storage from Silverlight 4
Hi
I just noticed something interesting - on the dev server if I can
see my __BlobUploadSessions__ created prior to forwarding my call on
to have the blobs created, if I skip that forward the sessions stay as
I would expect, if I do the same on the AppEngine I don't see the
__BlobUploadSessions__, it appears that they are not being created
successfully and that is maybe what is "Not found"
Thank you,
Patrick
