Yes. You could do that. But then that address would *be* the location of the file. Why would http://www.tmtm.com/cgi-bin/get_file.cgi?id=6 actually be any better than letting it be http://www.tmtm.com/docs/file.pdf?

If you don't want people to be able to fetch the file more than once, then that's a slightly different question. In that case you could wrap code around the get_file command to not allow the use of the URL more than once, but that's going to be more tricky than a simple database lookup to map the ID to the location.

Perhaps you could explain *why* you're trying to do this, and we might come up with a better solution.
