Have a look at this from the highly secretive CGI documentation :-)
When a file is uploaded the browser usually sends along some
information along with it in the format of headers. The information
usually includes the MIME content type. Future browsers may send
other information as well (such as modification date and size). To
retrieve this information, call uploadInfo(). It returns a reference
to an associative array containing all the document headers.
$filename = param('uploaded_file');
$type = uploadInfo($filename)->{'Content-Type'};
unless ($type eq 'text/html') {
die "HTML FILES ONLY!";
}
Dp.
