hyper-reverse-proxy 0.2.0

A simple reverse proxy, to be used with Hyper and Tokio.

A simple reverse proxy, to be used with Hyper and Tokio.

The implementation ensures that Hop-by-hop headers are stripped correctly in both directions, and adds the client's IP address to a comma-space-separated list of forwarding addresses in the X-Forwarded-For header.

The implementation is based on Go's httputil.ReverseProxy.
