Header Proxy

The header proxy listens on a port, injects the specified headers into every request and then forwards it.

This is not a production ready project. It was developed and is intended for development purposes only. It was originally created to mimic oauth2_proxy locally.

Usage

$ go run main.go --listen=0.0.0.0:3000 --forward=0.0.0.0:80 --header=foo=bar --header=fizz=buzz
2019/10/17 20:39:55 Listening on 0.0.0.0:3000
2019/10/17 20:39:55 Forwarding to 0.0.0.0:80
2019/10/17 20:39:55 Injecting headers map[fizz:buzz foo:bar]
