Is it possible to access the proxy address in the request handler? #282

I'd to access the proxy address that was used by the client to connect to the proxy and forward it as a request header.

For example, if I have a single instance of the proxy with dnsmasq resolving *.proxy.dev, serving team-a.proxy.dev and team-b.proxy.dev, I'd like to be able to inject a header with the proxy address on the way through.

I couldn't find a way to do this. Is it possible?

Yes, you can do something like https://github.com/rahulwa/camouflage/blob/master/proxy/proxy.go#L96

The part that I was struggling with was retrieving the proxy address itself. Is it possible to determine if the request was routed via team-a.proxy.dev versus team-by.proxy.dev (using the same proxy instance)?
