Preventing duplicate responses

Post by raemacleman » March 17th, 2009, 5:57 pm

Hi,

Can you tell me if WinSurvey rejects duplicate responses for the same survey from the same user, by setting cookies or by logging IP addresses, or some other means?

Thank you

The best and only really working way to avoid duplicate responses is the usage of user-ids and inviting participants with the module "My Respondents".

By default WinSurvey uses cookies to avoid duplicate responses; however this is not a secure way, since they can easily deleted by the user.
