How to avoid downloading a file directly from webserver ?

[Corobori]

Hi,

I need to provide a way to download a software and its corresponding
manual from a web page.

So far I have done the sign in page where people give their data. I
will then give access to a page with a link allowing to download the
required file(s).

My worry is how to avoid that somebody grabs the URL of the file and
send it to another for downloading directly from the server. What can
I do to avoid this ?

You can use the concept here: http://www.aspfaq.com/show.asp?id=2276 (Just
disregard the http_referer part, and replace that logic with the logic that
you're using on other pages to determine if the client requesting the page
is a valid, logged-in user.)
