Cookies

Hello,

I've created a cgi script to run a poll on my site. I use IP checking to see if someone has already voted. But if people are accessing my poll from behind a firewall, then they may have the same IP address. So instead of using IP check, I want to use cookie check.

Does any one know how to do this? Or can you at least tell me where to find information to do this?

Thanks.

using cgi with perl:

setting two different cookies:

use strict; 
use CGI qw(:standard);
use CGI::Cookie;

	my $title = "cookie1name";
	my $storycookie = "cookie2name";

	my $titlecookie = cookie(
	        -NAME    => $titlecookiename,
		-VALUE   => "$list{'title'}",
		-PATH    => '/',
		-EXPIRES => "+60d",
		);

	my $storycookie = cookie(
		-NAME    => $storycookiename,
		-VALUE   => "$list{'story'}",
		-PATH    => '/',
#		-DOMAIN  => 'localhost',
		-EXPIRES => "+60d",
		);

print "Set-Cookie: $titlecookie\n";
print "Set-Cookie: $storycookie\n";

'
in this example i put the userinput of form-field 'title' and 'story' into two cookies. if they come back to my site, the input is already there, using:

my ($titlecookie, $storycookie);
$titlecookie = $query->cookie("cookie1name");
$storycookie = $query->cookie("cookie2name");

if you wanna know, what -path, -expires stands for, read this FAQ.

i'm not sure, if cookies are the right way for your problem?
don't forget, user can ignore or delete your cookies, with that, they'd be able to vote several times for the poll. but i'm not sure, if there is another way to prevent that.
