kahlys/proxy

Simple tcp proxy package and executable binary in Golang.

⚠️ This code is for test purpose, it is sometimes ugly, it is not production ready, and the API will probably change. ⚠️

Installation

$ git clone github.com/kahlys/proxy/
$ cd proxy
$ go install cmd/tcpproxy/*.go

By default, the proxy address is localhost:4444 and the target address is localhost:80.
