Simple reverse proxy in Go

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)
        }

        handler := func(p *httputil.ReverseProxy) func(http.ResponseWriter, *http.Request) {
                return func(w http.ResponseWriter, r *http.Request) {
                        log.Println(r.URL)
                        r.Host = remote.Host
                        w.Header().Set("X-Ben", "Rad")
                        p.ServeHTTP(w, r)
                }
        }
        
        proxy := httputil.NewSingleHostReverseProxy(remote)
        http.HandleFunc("/", handler(proxy))
        err = http.ListenAndServe(":8080", nil)
        if err != nil {
                panic(err)
        }
}

Modified it to use struct and ssl

Helpful, ta, used this to transparently adjust some query parameters for certain requests.
