Workflow

Uploading

Create resumable upload on a server, pass session id to the client, let the client complete uploading. Client must notify the server when upload is complete. Once it's done - server checks this information and starts post-processing

Downloading

1. Client requests file to download
2. Server check authentication rights
3. On success - creates signed URL and returns 302 redirect + URL

Post-processing

Once initial file upload is completed - server may post-process the file. Ideally it would create a new file, which would act as a header or footer, save it in the same bucket with similar access rights. After that compose method should be called, which would concatenate files without using extra bandwidth
