Web Development: How can I allow a user to upload files directly to my CDN (Cachefly)?

I have a PHP web-application that allows users to upload images to my web site. I'm doing this using a simply HTML <form enctype="multipart/form-data">

However, instead of having those images uploaded to my web server - I would to have those images uploaded directly to my CDN (Cachefly - which is another server).

Is this possible ... to have a web-application allow a user to upload images directly to another server?

In case it helps, here's my PHP code:

$target_path = "/home/www/example.com/uploads/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    // file has been uploaded **LOCALLY**
    // HOWEVER, instead of it being upload locally, I would like the file 
    // to be directly uploaded to the CDN ('other' server)

} else{
    // error: file did not get uploaded correctly
    ....
}

i think in case of a CDN ... u will first have to receive files on ur server and then using the CDN API upload to their 'bucket'. i dont think u can upload directly to a CDN unless there is a way to map it as a directory on ur server.

• Moving / Uploading a file to a service or for you non-direct-accesable server is usually done by using the provider's API
• Moving / Uploading a file to a server 'owned' by yourself can be done by using PHP + FTP extensions (for more information: pear.php.net or pecl.php.net)
• Moving / Uploading a file to a server 'owned' by yourself and being one of many in a cluster is usually done by uploading the file temporary on 1 server and afterwards a .sh, .bash or whatever is called which activates further transfer processes to another server.

I don't think it's possible to directly upload to another server, but I could be wrong. I had a similar problem, and I used PHP's FTP capabilities (http://us3.php.net/manual/en/book.ftp.php). I still used my server as a middle-man, meaning I uploaded the files to my server, then FTP transferred them to the target server, and then deleted the file from my server.

You could recieve it on your webserver and then transfer it to the CDN via fileshare or FTP.

If the CDN is web-facing, you could re-direct the request to that server and send control back to your webserver form once the file is uploaded. It's probably better to do the file transfer in the back end though and keep the user connected to the web server.

Sure.

Somewhere in your code there is a "$target_directory" variable that needs to be set. It won't be called that, but depeding on how your function is set up it needs to be there -somewhere-. Just use an absolute path for the directory you want the files to land in. Also, make sure that directory is CHMOD'd to 777 so it can be written into.

Post your code and I can help more.

Yes amazon web services already allows you to upload to amazon S3 directly from the user's browser: Documentation: http://doc.s3.amazonaws.com/proposals/post.html

Additionally that S3 bucket can be exposed via the amazon CDN (or any other cdn that can point to a customer's origin server)
