This is still an issue and the relevant RFC part and a unittest would be as below. I would propose adding a new keyword argument with 401 as default value to ensure backwards compatibility with older versions. I can propose a PR if agreed and also improve test case since changing the hard coded status code from 401 to 407 doesn't seem to cause any failure.


https://tools.ietf.org/html/rfc7235#section-3.2

3.2.  407 Proxy Authentication Required

   The 407 (Proxy Authentication Required) status code is similar to 401
   (Unauthorized), but it indicates that the client needs to
   authenticate itself in order to use a proxy.  The proxy MUST send a
   Proxy-Authenticate header field (Section 4.3) containing a challenge
   applicable to that proxy for the target resource.  The client MAY
   repeat the request with a new or replaced Proxy-Authorization header
   field (Section 4.4).
