Per user vote behind proxy

[Burekas]

Hi, thanks for great application.

REMOTE_ADDR is always 127.0.0.1 and I don't need it to be unique, just per user voting.
Does application support that ?
Thank you.

Sometimes I'm getting errors like this when voting for the first time :

Traceback:

Hi!

There is no way to turn off ip checking currently. 😢
A fix would be to configure your reverse proxy to set the correct ip as `REMOTE_ADDR.
