[thelist] Downloading a file without giving the link

[Kevin]

Hello,

I am in the process of developing a perl script that will allow downloading
a zip file only once. My problem is that if I give out the link, I will not
have any control and people will be able to download the file many times.

What is the best way to handle a situation like this? Can the binary data be
send via a special header?

TIA
