Modifying Connection header

[Neschastje]

import psutil
import time
from browsermobproxy import Server

server = Server('../resources/browsermob-proxy-2.1.4/bin/browsermob-proxy')
server.start()
proxy = server.create_proxy()
print(proxy.proxy)
proxy.headers({'test': 'close'})
#proxy.headers({'Connection': 'close'})

I'm using code above to start a proxy server for my browser to add/modify headers. Unfortunately, I can't do this with "Connection" header. Is there any way to do this?

I have the same problem. browsermobproxy.client.headers(dict) doesn't seem to be work. Anyone has solved this?
