Remote file tranfer eating both server's bandwidth?

[TxFrog1999]

I've created a script to retrieve files from another server. The script is run on Server A and the files reside on Server B, but I've just found out that when using the script on server A both get hit with the bandwidth. Its as though the file is being opened on Server B, transfered to Server A then sent to the user instead of opening a direct link from the user via the script on Server A to the file on Server B.

Lost yet? Anyone have a clue why this is happening? For reference sake here is a snippit of the code I'm using... perhaps it needs to be changed:

<?php

// set variables here
// $file
// $filename
// $size
// end setting variables

header("Content-Type: application/whatever");
header("Content-Disposition: attachment; filename=$filename");
header("Content-transfer-encoding: binary\n");
header("Content-length: " . $size . "\n");
$fp=fopen($file, "r");
fpassthru($fp);

?>

Yes, I think the moment you used fopen, server A retrieved the file, and fpassthru sent it to the browser(from server A).

Use:
header("location: $file");
instead of
$fp=fopen($file, "r");
fpassthru($fp);

Hope I'm not missing something, usually do..

bye!

Thanks for the advice I'll try it out and report back. I'm still working on getting a better understanding of PHP and file transfer protocols.

Thanks for the help
