[quote author="phybertek" date="1218190812"]Is there anyway to detect if the client is a program accepting and clearing cookies?

I think you application will run on intranet. so my suggetion is track the IP address or client mac address. but there is a limitation "number of votes count per PC".

If you want to run this on internet then have to use unique id because I don't think there is any program available to detect accepting and clearing cookies.
