How can we restrict user from duplicate voting in websites
posted 8 years ago
I have just logged into one website and participated in a poll. I could able to vote to my need. I tried again to vote it has told me that you have voted already. Ok cool, it seems to be good. I tried again by clearing cookies and cache, still i could not vote. Even i tried by changing browser from mozilla to IE. Still i could not vote. It is fabulous to me. Can anybody make me understand underlying logic in preventing duplicate votes.
