Usage

Make sure docker-proxy server is already running
Make an HTTP request or TCP connection
(Optional for HTTP mode) Set X-Target-Host header with the target host (ex: https://google.com or http://another-container)
Send this HTTP request to http://{docker_proxy_local_address}/... or TCP connection to docker_proxy_local_address

Notes:

Make sure docker-proxy is running as a container and connected to particular network if you want to proxy other containers
