In general, you always want to die gracefully from within a web script so
the error is logged and the user doesn't get an icky 500 error page.
For example, in database apps I write, for any error, I tell the user the
database is unavailable and I log the error.
The following has worked for me when dealing with POST_MAX:
use CGI qw/:standard/;
$CGI::POST_MAX=1024 * 10;
$CGI::DISABLE_UPLOADS = 1;
$| = 1;
my $page = new CGI;
print $page->header;
$run = $page->param('RUN');
if (!$run && cgi_error()) {
# do whatever you do for an error
&dieWell ("413: Max Posting surpassed.");
}
sub dieWell {
my $message = shift;
# remember to print proper headers if not done by now
print "$thanks_for_playing_message\n";
# do logging of $message if you want, send yourself email, whatever
&footer; # end my html -
exit;
}
