There exists a voting mechanism that you want to restrict to simply allow one election by user.

We have attempted to validate by Ip, but however , whenever we obtain the user's Ip within the applicational server it shows always the apache Ip (we've two applicational servers with apache before them).

We're using ColdFusion variable CGI.REMOTE_ADDR to obtain the user IP.

Anybody understands how to fix this?

We wish to avoid using periods or snacks.

Thanks ahead of time.

You most likely desire to use the X-Forward-For header header
rather than the origin ip, presuming your apache instances are putting it in to the request.
