[New-bugs-announce] [issue24964] Add tunnel CONNECT response headers to httplib / http.client

[Thomas]

New submission from Thomas:

When using httplib / http.client to connect to an HTTPS website through a proxy (by making a tunnel with a CONNECT request), there is no way to retrieve the HTTP headers which the proxy sends back in response to that CONNECT request.

This becomes a problem when using rotating proxy providers like ProxyMesh, who send useful information in those headers (for instance, "X-ProxyMesh-IP" contains the IP address of the proxy, which is necessary to keep the same address throughout the session).

It would be nice to save those headers in a property of the HTTPConnection class (e.g. self._tunnel_response_headers), which would be set up inside the _tunnel method (as proposed in the attached patch, lines 748 and 827-831). This would allow to get the headers back and/or pass them to a higher-level library (such as requests).
