If you are looking for the closest thing to secure as you can without requiring a log-in.. the do track both cookies and IP. There are two things with just tracking IP.. that you should know about anyway.. I If you have a client on a network behind NAT or behind a firewall.. and he tells his co-worker behind the firewall.. then they will probably both have the same IP address.. so it won't let his co-worker vote.. and Dial up users get a new IP address when they disconnect and reconnect(a process that takes all of 30 seconds). The point is though.. that while tracking cookie and ip is a good solution.. it can't beat having the user log-in for higher security type polls. For all other polls/surveys where you want the most security that you can without requiring the user to log-in.. then IP and cookie is as high as you can go as far as I know.
You might also look into getting one of those images that have numbers that only humans can read.. so people will not be able to program bots that will simply submit over and over again. -Zine -----Original Message----- From: Ewok [mailto:[EMAIL PROTECTED] Sent: Sunday, July 20, 2003 1:53 AM To: CF-Talk Subject: Re: track duplicate survey votes store cgi.remote_addr with each submission and dont let the same IP vote twice its easy to delete cookies and vote again. It's more of a pain to change ur ip to vote again and if someone does... hey... they've got nothing better to do anyway : ) "Tim Laureska" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > I have a basic yes/no survey question at a site that is not password > protected (we'd like to keep it that way so as not discourage response) > > Our recent survey question was obviously jumped on by somebody who > placed many more yes votes than would be realistic for the issue .... > I'm trying to figure out the best way to track duplicate votes if this > is possible ... this may be a simple problem but its new to me and was > hoping someone could give me a "best way to do this" nudge in the right > direction > > Thanks in advance > Tim Laureska > > > > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Archives: http://www.houseoffusion.com/cf_lists/index.cfm?forumid=4 Subscription: http://www.houseoffusion.com/cf_lists/index.cfm?method=subscribe&forumid=4 FAQ: http://www.thenetprofits.co.uk/coldfusion/faq Signup for the Fusion Authority news alert and keep up with the latest news in ColdFusion and related topics. http://www.fusionauthority.com/signup.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
