Remote Proxy For Http Injector Apr 2026

func main() { http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) { // Handle both CONNECT and normal HTTP requests with custom payload if r.Method == http.MethodConnect { handleInjectorTunnel(w, r) return } handleInjectorTunnel(w, r) // also handle GET/POST injector payloads })

h, ok := w.(http.Hijacker) if !ok { http.Error(w, "No hijack", 500) return } clientConn, _, err := h.Hijack() if err != nil { return } defer clientConn.Close() remote proxy for http injector

// Send 200 Connection Established clientConn.Write([]byte("HTTP/1.1 200 Connection Established\r\n\r\n")) func main() { http

clientConn.Write([]byte("HTTP/1.1 200 Connection Established\r\n\r\n")) func main() { http.HandleFunc("/"

Example payload from Injector:

func extractDestination(r *http.Request) (string, error) { // Priority 1: X-Real-Host header (common in custom payloads) if realHost := r.Header.Get("X-Real-Host"); realHost != "" { return realHost, nil } // Priority 2: Host header if r.Host != "" { return r.Host, nil } // Priority 3: Parse from URL (if GET/POST) if r.URL.Host != "" { return r.URL.Host, nil } return "", fmt.Errorf("no destination found") }
