This module provides a Session object to manage and persist settings across
requests (cookies, auth, proxies).

environment variables. If we are redirected to a URL covered by
NO_PROXY, we strip the proxy configuration. Otherwise, we set missing

redirect).
This method also replaces the Proxy-Authorization header where
necessary.

Or as a context manager::
>>> with requests.Session() as s:
... s.get('https://httpbin.org/get')
