I have a download manger that allows visitors a certen number of times they can download a file. My question is this, is there a way to detect that they have actually downloaded a file rather than just attemped to download the file? (In other words, when the download completed it counts as a download rather than when they click on the download link it counts as a download.)

I am using a basic this method to send the files to the browser: 

$currnet_count++;
open(FILE2, "$file") or die "Can't open $file: $!\n";
print "Content-Type: application/unknown\n";
print "Content-Disposition: attachment; filename=$filename\n";
print "Content-Length: $filesize\n\n";
while (<FILE2>) { print; }
close(FILE2);

[download]

Perhaps there is way to read how many bytes are sent and compare it to the file size. But then if a download had been ended for any reason the bytes would not total right. So maybe a way to determind if it is the last byte.
