FYI, I've just put up a PR against Miniflare to fix a small bug related to the code you've copied: https://github.com/cloudflare/miniflare/pull/382

Not sure if it affects you here, but worth testing.

Good catch, resolved

(Provided tests pass) I'm going to merge this in now

Doesn't look like we have proxy server tests? Maybe this is something we should address...
