TLS passthrough upstream proxying

[mtsvetanoff]

Greetings.

Some context:

1. TLS passthrough is enabled for all hostnames
2. All requests are configured to go through an upstream proxy

In these circumstances one would expect that a request would not be modified by Mockttp, but it will still respect the upstream proxy configuration.

But it appears that when TLS passthrough is enabled then the requests are not being routed through an upstream proxy.

Is there a way I could configure Mockttp to behave in the expected way?

Regards
