Super simple tool to create a SSL proxy in front of an http server. (Let's say, for instance, your app requires SSL which is normally provided by a upstream LB/proxy, but you want to make it work in your dev environment).
The credit goes to the standard library for implementing the core of what this provides.
simplehttpsproxy sets X-Forwarded-For header on the request to the backend.
$ go get github.com/yannk/simplehttpsproxy
$ simplehttpsproxy
or -
$ simplehttpsproxy -host=proxyhost.com -cert=cert.pem -key=key.pem -listen=localhost:4443 -backend:8080
