I have a feeling that it’s currently just working by accident; e.g. it's because the TCP connection to the control server exists before we start mitmproxy and hence the connection doesn’t get passed to its NETransparentProxyProvider or something. To be on the safe side, though, I’ve added a check in the mitmproxy addon so that we only mess with stuff for ports 80 or 443 + # + # Note that in the current setup with ably-js, the test suite and the Ably SDK run in the same process. We want to make sure that we don’t intercept the test suite’s WebSocket communications with the interception proxy’s control API (which it serves at 127.0.0.1:8001), hence only targeting the default HTTP(S) ports.
