The code: 

$type = $query->uploadInfo($filename)->{'Content-Type'};

[download]
returns the Content-Type header the browser added to the upload. Basically, it's what the browser (or the user's computer) thinks this file is. It's not fool-proof however, and browsers are not required to include it.

See the CGI documentation for more information.
