Go redirect location

Code

package main

import (
    "log"
    "net/http"
)

func redirectHome(w http.ResponseWriter, r *http.Request) {

    http.Redirect(w, r, "/", 301)
}

func main() {
    http.HandleFunc("/", redirectHome)
    err := http.ListenAndServe(":8123", nil)
    if err != nil {
        log.Fatal("ListenAndServe: ", err)
    }
}

Test CURL output
