Force download WITHOUT readfile?

Is it possible to force a download without using the readfile
function?

My website setup consists of my server that serves the web pages plus
a high-speed file server elsewhere on the internet that servers my
files. I'm currently using header("Location: abc.com") to redirect my
users to this other site but can't force a download.

I can get it to work using readfile() but that means the file moves
from the high-speed server through my webserver and then to the user,
which I don't want.

Here's my current setup:

header("Content-Type:application/force-download;name=\"".$path_parts["basename"]."\"");
header("Content-Disposition:attachment;filename=\"".$path_parts["basename"]."\"");
header("Content-Length: $size");
header("Content-Transfer-Encoding: binary");
header("Location: ".$path["path"]."");

The above works just fine but doesn't force the download. Changing the
header("Location: ".$path["path"]."") to readfile($path["path"])
forces the download but now the file moves through my webserver and I
don't want that.

Thanks

You tell me, is there another way than a UserAgent that downloads file(s)?

Oh, your going to play with the Content-type... This has been discussed
many times before in this group. So i'm pretty sure you'll find out why
it's impossible by definition.

On the first site, you redirect them, not directly to the file, but to a
download.php on the second server.

On the second server you place your download.php that outputs the
headers and the readfile...

I did scour the entire group and though everyone's answer was to use
readfile, no one specifically said that there is no other way. So I
guess this post is basically the "there's no other way" post.

Yeah, that's pretty much what I thought. Unfortunately, the second
server is commercially owned which means I have little input
configuration-wise. So I guess I'm stuck with a redirect.

Thanks anyway
