For info only, in case it was missed earlier.

The AWS Multipart incremental upload referenced earlier started life as a request for Content-Range on PUT requests [1]. Also referenced in that thread is the Microsoft Azure use of Range headers in PUT as a solution (probably a spec extension/violation ?). Interesting to note that the reasoning from AWS for using multipart chunks is the difficulty with reassembling the parts in a cloud environment where parts of a S3 bucket could arrive concurrently from distributed hosts.
If this has already been looked at and considered, then sorry for the noise.

> Use cases: 
> 1. Large file upload - With high speed internet connections, advent of cloud and HD going mainstream, Sling should support large files (> 2GB) upload.
> 2. Fault tolerant uploads - Sling should provide capability to resume upload from failure point. It should not require client to restart the complete upload process. 
> 3. Faster upload: Sling should support its clients to initiate multiple connection and upload file chunks in parallel.
