How to write a CGI script that generates a semicolon separated file

[ATC]

When generating web content on-the-fly, the standard HTTP header used is "Content-type: text/html". However, this means the user has to actively click "File" and "Save as..." to get a file save dialogue. Furthermore, the default filename is the same as the CGI script filename.

Use the following HTTP header instead:

Content-type: application/octet-stream
Content-Disposition: attachment; filename="filename.ext"

This will cause most browsers to pop up the file "Save as..." dialogue automatically. Note that you may NOT specify a path.
