Summary

urllib3 is a user-friendly HTTP client library for Python. When using urllib3's proxy support with 'ProxyManager', the 'Proxy-Authorization' header is only sent to the configured proxy, as expected. However, when sending HTTP requests without using urllib3's proxy support, it's possible to accidentally configure the 'Proxy-Authorization' header even though it won't have any effect as the request is not using a forwarding proxy or a tunneling proxy. In those cases, urllib3 doesn't treat the 'Proxy-Authorization' HTTP header as one carrying authentication material and thus doesn't strip the header on cross-origin redirects.
