flat networking mode.....request is going to proxy...even though i have set no proxy for localhost......

Using flat networking mode in OpenStack installation.....I have set no proxy for local host in /etc/environment file......even then request (http://10.14.77.196:8773/services/Cloud/) is going to proxy ......I am checking this using wireshark..........why so??

This is my /etc/network/interface file.............
