POST url to S3 directly

Given a url of a downloadable file, such as:

http://zannee-docs.s3.amazonaws.com/rockefeller-summary.pdf

Is there a way to POST / PUT this directly to S3? Or is it necessary that I do:

# download the file
requests.get(url, stream=True)

# save the file locally

# upload the local file to S3
s3.upload_file()

If there is a way to upload it directly to S3 (without having to download it and re-upload it to S3), how would I do this?

It is possible to use pre-signed URLs to PUT objects directly to S3. I don't believe you could get it work with POST because POST has to encode the body of the request but perhaps there is a way to do that, too. This SO thread should be useful:

Yes, but only if the source URL is also hosted in S3, and your S3 key can access it. (The documentation doesn't say this explicitly, but I think the source object needs to be stored in the same region as well.)

http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectCOPY.html

Since you're using boto, the specific API you'll want is boto.s3.key.Key.copy().
