Using send_file to download a zip file to browser without rails server being involved

I am using the following snippet to allow a user to download a zip file. The path here is a link on the S3 bucket. I want to confirm if the file would be directly downloaded from S3 to the browser or would it first be downloaded to the rails server & then streamed from there?

If the latter, what is the best way to avoid that?

path = "#{file.download_attachment.path}"  
send_file path, :type => 'application/zip',
                :disposition => 'attachment',
                :filename => "#{file.name}.zip"

The accepted answer on this question: Difference between rails send_data and send_file, with example will explain you the difference between send_file and send_data.

If you like to stream something, use send_data. If you like to send an already existing file, use send_file, so your code seems to work the way you like ;)
