Are you using Hostname Based SSL? Due to... who knows what... Hostname Based SSL will not allow you to get a users IP address. Instead, it will return the same few every time. Looking at different headers, etc. won't help.
Sucks, I know. If you realllllly need a users IP address, you can use an external service (or build one yourself if you're feeling fancy) ... such as jsonip.com. (jsonip.com/callbackmethodname for JSONP callbacks) -- You received this message because you are subscribed to the Google Groups "Heroku" group.
