I don't know about any way to prevent it than to track how much has been
downloaded for the whole POST and
when you get past a certain number of bytes, stop, drop the input
connection, and return a HTTP 413 (POST Too Large) code.

I do not know if the validator does this.

This is what Perl's CGI.pm module does in its newest versions, (2.66 does
it, 2.56 I don't think so) so it makes things easy for me.

use CGI;
$CGI::POST_MAX = 1024 * 120;  # max 120K posts
