# Custom Headers
'''
Authorization headers set with headers= will be overridden if credentials are specified in .netrc,
which in turn will be overridden by the auth= parameter.
Authorization headers will be removed if you get redirected off-host.
Proxy-Authorization headers will be overridden by proxy credentials provided in the URL.
Content-Length headers will be overridden when we can determine the length of the content.

Cookies are returned in a RequestsCookieJar, which acts like a dict but also offers a more complete interface,

# Redirection and History

By default Requests will perform location redirection for all verbs except HEAD.
We can use the history property of the Response object to track redirection.
