Here's the script. I only hide the HTML portions.

I'm using:
Apache/2.0.44 (Unix) mod_perl/1.99_08 Perl/v5.8.0 PHP/4.3.1

----------------------------------------------------------


#!/usr/bin/perl -w

$buffer = $ENV{'QUERY_STRING'};

@pairs = split(/&/, $buffer);

foreach $pair (@pairs) {
    ($name, $value) = split(/=/, $pair,2);
    $value =~ tr/+/ /;
    $value =~ s/%(..)/pack("C", hex($1))/eg;
    $FORM{$name} = $value;
}

#verify that the field was sent
if (defined($FORM{'referencia'})) {
    $referencia = $FORM{'referencia'}
} else {
    print "Location: SOME URL HERE\n\n";
    exit(1);
}


# ---------------
# set STDOUT HOT

{
   my $ofh = select STDOUT;
   $|++;
   select $ofh;
}


print "Content-Type: text/html\n\n";

$arq_produto = '/var/www/default/clientes/gecele/db/'.$referencia.'.txt';


    open(FILE,"$arq_produto") || &error('ocorreu um erro ao ler o arquivo');

    $_ = <FILE>; # set the name of the obs file
    chop($_) if $_ =~ /\n$/;
    $arq_obs = '/var/www/default/clientes/gecele/db/'.$_;

    $_ = <FILE>; # set the name of the image path
    chop($_) if $_ =~ /\n$/;
