PHP Force Download of Remote File

Question

Hello all,

I have a bunch of videos stored on my Amazon S3 storage. I'm working on creating a PHP script, very similar to the one here, where users can download the videos to their hard drive.

I'd like to use something like this:

<?php
$file_name = $_GET['file'];
$file_url = 'http://www.myamazons3.com/' . $file_name;
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary"); 
header("Content-disposition: attachment; filename=\"".$file_name."\""); 
readfile($file_url);
exit;

However, I am under the impression that this increases the bandwidth because the video will be coming through my server.

Any ideas on how I might be able to force the download of these videos, while avoiding reading it first through my own server?

Many thanks!

Answer 1

header('Location: ' . $file_url);

Take a look at the S3 API Docs, and note the header values that you can set. Amazon will send these when the file is requested: http://docs.amazonwebservices.com/AmazonS3/latest/index.html?RESTObjectPUT.html (the same parameters can be sent with a POST to update an existing object)
