Change upstream proxy for https flow

[Jake232]

@wmrowan You got this working? I am using the latest version but it seems HTTPS still uses the default proxy. As described here:

Upstream Proxy HTTPS

I have my script changing the upstream proxy for HTTP connections, but it seems to fail for HTTPS connections. Here’s a basic stripped down example. The script works fine for http://api.ipify.org/, but fails for https://api.ipify.org/. With HTTPS I see the following, which shows the upstream proxy wasn’t changed. Server connection to default_proxy:8888 failed: Error connecting to "default_proxy": [Errno 8] nodename nor servname provided, or not known Running Command: mitmdump -s utilities/…

Got any insight?
