Multi-request file uploads
Clients can create an upload session to allow large upload payloads to be broken up and transferred to the host over multiple requests. Requests must provide the payload in sequential order. Each request resumes, in byte order, where the previous request finished. The upload session payload contains only chunk frames, and the entire upload session is referred to by a final PutChunkedFile call that contains all of the frames in the upload session. If the PutChunkedFile call fails (such as in the case of a sequence number mismatch), the upload session remains, allowing the client to try a new PutChunkedFile call without having to retransmit the entire upload session payload.
To upload a set of chunks using an upload session, follow the steps in these articles:
