Go-Go

And what is it about Request.ServerVariables("LOGON_USER"), is there any way to get this from users.

This is another solution what I think but then I need request from visitors to be registred and thy want bother with registration proces and cheater will create more than once account and he will be able to vote more then once. I need to get some unique info from user what he can't change and what it could be?

I have asp poll and i want to prevent multiple votes. I try with cookies and IP tracking but have no results. User simply delete cookies and reconnect (after disconnecting and connecting he get new IP adress) and he can vote again.Second solution I try is Request.ServerVariables("LOGON_USER"), (Request.ServerVariables("AUTH_USER"), Request.ServerVariables("REMOTE_USER") store them in database and block cheater. Problem is at my server administrator becouse he won't enable anonimus logon for security reason. What else can I do to prevent multiple votes. Sorry at my english, I hope you can understand my problem and found some solution.
