Well, there’s a lot of different ways you could do this. You want to
send the link to individuals who have paid, and you want them to be
able to download the file, but not share the link with others. Is
that about right?
How do you track the individuals who have paid? Do you have some sort
of database on your Web server that could be queried for this
information? How many of these links do you need to send out at a
time? How much work are you willing to do yourself, and how much do
you want this to be automated?
One way to manage this is with a PHP script (or another language)
that can look up records in a database. You send out links to your
customers that include an identifier string, maybe: <http://
yourserver.com>. Your customer clicks
on that link, the Web server sends that request to your script, which
looks to see if that code (123abcz) has been used yet. If it hasn’t,
then it forwards the request to the actual file and marks that key as
used. If it has, then it forwards the browser to a Sorry page, which
includes instructions for requesting a new download.
That’s a drastic oversimplification of how this would work, there
would need to be some leniency for multiple requests in a short
period of time by the same IP address, since a person might suffer an
interrupted download for some technical reason outside of anybody’s
control.

I’m using an autoresponder system (Interspire SendStudio) that
sends a set of lessons every week to subscribers. Before getting
started, the user has to fill in a simple form and he gets an
automated answer with password instructions to open the file.
Problem is that I don’t want him to go back to the site and
activate any download, but to be able to get the file straight
ahead. These would be too many clicks.
The system doesn’t allow me to upload the file and to send it
automatically. So I guess I need an address on my webhost in the
public_html, and put this address on the email that is sent,
correct? But I’m not sure. Any great idea there?
