This fragment is from a login-protection script I wrote to test a system I'm eventually planning to deploy on my own domain. It works on my server's FreeBSD installation, with IE5.5, NS4.xx, and NS6.xx clients.

use CGI;
use CGI::Carp qw(fatalsToBrowser);

sub NiceGetFile
{
  my ($Filename) = @_;
  my $RawHTML = "";
  if (open(FILE,"<".$Filename))
    {
    binmode(FILE);
    my $Position = sysseek(FILE,0,2);
    if ($Position)
      {
      sysseek(FILE,0,0);
      sysread(FILE,$RawHTML,$Position);
      }
    close(FILE);
    }
  return $RawHTML;
}

# probably should set the CGI config to blast excessive 
# POSTS here

my $DynPage = new CGI;

# Do anti-leeching code immediately

my $file = 'Demo.zip';

my $ZIPFile = &NiceGetFile('ZIP/'.$file);
unless($ZIPFile)
  {    # inform user and email admin
# ....
  };

# NOTE: could use Content-MD5 header here
# NOTE: change the type-header to the real MIME-type
print $DynPage->header(-type=>'application/zip',
                       -Content_Length=>length($ZIPFile));

binmode( STDOUT );
print $ZIPFile;
