[net/http.Request] How to get the original request URL path?

[yic...@gmail.com]

Hello, 

My Go web service will serve traffic from a redirect, from a url like http://www.original_host.com/original_path/. 

Any requests that goes to the URL pattern http://www.host.com/map/* will be served by my Golang web service as root path "/".

I am writing the web service using go-martini, but I am having trouble retrieving the original request URL. Inside the go-martini app, it seems the data in http.Request are all in the context of the local/relative path. Is there a way to get the full request path? 

Thanks,

YI

Sender := req.Header.Get("X-Real-IP")

This seemed to work for us....

That's a non-standard header. Certainly not every client (if even very many) will send it.

More information?

• Have you tried r.URL.Host + r.URL.Path (see http://golang.org/pkg/net/url/#URL)
• Or are you having issues getting the *host* due to sitting behind a reverse proxy? In which case you'll need to add (e.g; for nginx) X-Forwarded-For $proxy_add_x_forwarded_for to your webserver config

I am assuming it's the former though.
