I need to use urllib3 with proxy which requires authorization
http = urllib3.ProxyManager('http://host:port', headers={ 'User-Agent': UA_CHROME} )
I have tried to pass proxy headers with login and password like this
proxy_header={'login': login, 'password': pass}
and I used options in these answers How to handle proxies in urllib3 but it did not help. How can I authorize my proxy in urllib3?
