Multipart uploading file by the PUT method

[abozhiy]

I need to implement multipart upload file to S3 with presigned part URLs, for each part I need to pass file in request body by the PUT method, but as I understand it, async-http expects an array of strings for the body. Is it possible to pass a file inside the request body and how to do it?
Thank you.

I think I've found solution:
::Protocol::HTTP::Body::File.open(part_path)

Looks reasonable!
