Google Analytics with nginx reverse proxy

[fakrulalam]

I am using NGINX as reverse proxy and forward the traffic to Apache server
where Google Analytics is configured. I have configured proxy_set_header and
from Apache server I can view users IP address. But in Googel Analytics
users session droped. I am wonder where there is any  other configuration
need to be done?

Thanks 
Fakrul
