Golang Auth proxy example

This is just an example on how to use the httputil.ReverseProxy type provided in the golang standard library.

1. Open a terminal in the root folder and run go run target/main.go. This will start the target server. It will only respond to request from localhost:8081

2. Open another terminal in the root folder and run the following commands:

# first export some env variables
export SCHEMA="http"
export HOST="localhost:8080"
export Auth="123456"

# then run proxy server
run go proxy/main.go

This will start our auth proxy in localhost:8081 and will redirect traffic to http://localhost:8080 only if there is an header like "Auth: 123456"

3. Open another terminal and start making some requests

4. Have fun
