PHP Pass external download to user

I was wondering if there was any way in PHP to pass an external download off to a user? What I would like to do with the script is depending on certain conditions, send the user a file from server A or server B. However, I don't want the user to know the direct url to either server.

Ex: User visits (which is on server C): http://example.com/download?id=1234 Server A's Address to file: http://servera.com/1234.exe Server B's Address to file: http://serverb.com/1234.exe

Is there a way, that when someone visits http://example.com/download?id=1234, to send them the download of the other servers without giving the user the direct URL? I know I can do a file([external file here]). But I do not want all the bandwidth going through server C. Server C is pretty much just a redirect.

Thanks, James

You may be able by using NAT or a Proxy. But this will be very difficult.

Only by modifying the headers it probably won't work.

EDIT: No, I think, you would have to add a proxy for all your servers at once (e.g. gateway).

The client must know at some level which server they are downloading from, otherwise they wouldn't be able to connect to it.

EDIT:

If you don't want the address bar of the browser to change, you can try using the Content-disposition header like so:

header("Content-disposition: attachment;filename=1234.exe");
//then output the file contents

Note: this PHP script has to be on server A and server B. So server C will redirect to either http://servera.com/download.php or http://serverb.com/download.php.
