Simple reverse proxy in Go (forked from original to use a struct instead of a closure)

revprox.go

package main

import(
        "log"
        "net/url"
        "net/http"
        "net/http/httputil"
)

func main() {
        remote, err := url.Parse("http://google.com")
        if err != nil {
                panic(err)
        }

        proxy := httputil.NewSingleHostReverseProxy(remote)
        // use http.Handle instead of http.HandleFunc when your struct implements http.Handler interface
        http.Handle("/", &ProxyHandler{proxy})
        err = http.ListenAndServe(":8080", nil)
        if err != nil {
                panic(err)
        }
}

type ProxyHandler struct {
        p *httputil.ReverseProxy
}
func (ph *ProxyHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
        log.Println(r.URL)
        w.Header().Set("X-Ben", "Rad")
        ph.p.ServeHTTP(w, r)
}

This is why github is awesome - top effort and lovely code! Thanks :)

thanks :)

you are missing the r.Host = remote.Host part from original gist

Great! 👍
