Download counter

Thu Mar 4 14:07:18 EST 2004

people why does this not work??

I have tried to write a download manager (counter) for my website
called something like this: http://<server>/cgi-bin/download.py?FileID=1

I do get a download popup but the download is broken. Someting is not right
and I don't know what.

Excuse my sloppy code... It is stil in test.

Code below, help appreciated.
