go-tee

split traffic like a tee in order to send traffic to a debug system

Going over logs and metrics sometimes is just not enough. go-tee is basically here to help debug a production system. When you see a spcecific http error code happens in production you can fork it with harming the original traffic with go-tee and send the original http request to another system for debugging.
