Compatibility code to be able to use `cookielib.CookieJar` with requests.

��Zed��ZRS(s�Wraps a `requests.Request` to mimic a `urllib2.Request`.

    The code in `cookielib.CookieJar` expects this interface in order to correctly
    manage cookie policies, i.e., determine whether a cookie can be set, given the
    domains of the request and the cookie.

    The original request object is read-only. The client is responsible for collecting
    the new headers via `get_new_headers()` and interpreting them appropriately. You
    probably want `get_cookie_header`, defined below.
