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

revprox.go

package main

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

type Proxy struct {
    target *url.URL
    proxy  *httputil.ReverseProxy
}

func (p *Proxy) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    log.Println(r.URL)
    r.Host = p.target.Host
    //w.Header().Set("X-Ben", "radi")
    p.proxy.ServeHTTP(w, r)
}

func main() {
    // Replace 'target' with the URL of the server you want to proxy to
    target, err := url.Parse("https://example.com")
    if err != nil {
        panic(err)
    }

    // Create a new ReverseProxy instance
    proxy := httputil.NewSingleHostReverseProxy(target)

    // Configure the reverse proxy to use HTTPS
    proxy.Transport = &http.Transport{
        TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
    }

    // Create a new Proxy instance
    p := &Proxy{target: target, proxy: proxy}

    // Start the HTTP server and register the Proxy instance as the handler
    err = http.ListenAndServe(":3000", p)
    if err != nil {
        panic(err)
    }
}
