in thread mod_perl give 404 not_found with content

Unfortunately it doesn't work for me.
My mod_perl/startup.pl looks like this:

use strict;

use Apache::DBI;
use Apache2::Request;
use File::Slurp;
use Net::SMTP;
#use CGI;
#CGI->compile(':all');

Apache::DBI->connect_on_init('DBI:mysql:dbname::localhost', "user", "*
+*****",
        {
                PrintError => 1, # warn() on errors
                RaiseError => 0, # don't die on error
                AutoCommit => 1, # commit executes
                mysql_enable_utf8 => 1,
                # immediately
        }
) or die "Cannot connect to database: $DBI::errstr";

And then there's a myscript.pl in the mode_perl dir that looks like this:

#!/usr/bin/perl

use strict;
use warnings;

my $r = shift;
my $cgi = Apache2::Request->new($r);
my $QUERY;

if ($cgi->param('q') =~ /^([a-zA-Z0-9\ \.\,\-_\:\;]+)$/)
{
    $QUERY = $1;
}


my $ruri = $ENV{'REQUEST_URI'};
$ruri =~ s/%([0-9A-Fa-f]{2})/chr(hex($1))/eg;
...
...
        if ($sth->rows == 0)
        {
                #$r->err_headers_out->set(Location => "$ruri/");
                $r->status(404);

                #$r->status(Apache2::Const::NOT_FOUND);
                $r->content_type('text/html');
                $r->print(<<"END");

END
                ModPerl::Util::exit(0);
        }
