Wrong URL generation behind proxy

[rafamanzo]

Have a look at mezuro.org.

It produces urls for push notifications as: http://mezuro.org:8085/repositories/<ID>/notify_push. This is the port it is running behind the proxy while the notifications should get pushed to 80.

Some goes for logging in hanging forever because devise tries to redirect forever to http://mezuro.org:8085/en. Have a look at the log:
