php question about headers

[keegan]

Hi guys. I have a simple question. I'm streaming one file from one host to another, for various reasons. I have, say, a .rar file on one host, and the download link is on another. Let's call the place where the fle is host A, and where the lin kto the file is host B. Im doing this using the following code, on host A:

        $file = "http://www.myhost.com/file.rar"; 
        header("Content-disposition: attachment; filename=".basename($file)."");  
        readfile("$file");

Now i'm curious as to whether or not this counts as bandwidth for host A, as well as for host B. I assume it's like adding the google logo to my website, it uses google's bandwidth, not mine. However, in the download window, it says "Downloading file from Host A." But, that could just be because it's streaming it. So... does anyone know? :) *.* cin >> knowledge;
