I would go for the 3rd alternative. There are several ways to
"stream" the file with the use of headers.
This way you can validate the user securely with your logon system,
and you can place the files outside the viewable web content.
Typically oputside your www / public_html folder.
I use this myself in an application I use, streaming files at 50MB
does not use alot of resources at all, atleast not the way I use.
My use for the script is to serve high resolution images to several
customers, often TIF images up to 50MB and larger.
Heres the code I use :
$distribution= "filepathonserver";
if ($fd = fopen ($distribution, "r")){
$size=filesize($distribution);
$fname = basename ($distribution);
header("Pragma: ");
header("Cache-Control: ");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$fname."\"");
header("Content-length: $size");
while(!feof($fd)) {
$buffer = fread($fd, 2048);
print $buffer;
}
fclose ($fd);
exit;
}
