the problem of dynamic ip address
Posted: Thu Nov 11, 2004 5:08 pm
Hello,
i want to create a page where everyone could vote for his favorite music group. That is, everyone could vote for his favorite group. As a result the group which will get most votes become a winner.
So, i would like to ask: "How could i make the page that nobody could vote two, three, four .... times".
Tirst of all i read everyone's ip and put in database. And the computer which ip is in database could not vote second time.
Everything is fine, but what shall i do if the person who votes has a dynamic ip address. He could vote several times? What is the solution?
