GoLang の「http.DefaultClient.Do(req)」はサーバーが利用できない場合に自動的に HTTP リクエストを再試行しますか?

<code class="go">package main

import (
    "fmt"
    "io/ioutil"
    "log"
    "net/http"
)

func main() {
    var (
        err      error
        response *http.Response
        retries  int = 3
    )

    for retries > 0 {
        response, err = http.Get("https://non-existent") // Replace with your server URL

        if err != nil {
            log.Println("Request failed", err)
            retries -= 1
        } else {
            break // Request succeeded, exit the retry loop
        }
    }

    if response != nil {
        defer response.Body.Close()
        data, err := ioutil.ReadAll(response.Body)
        if err != nil {
            log.Fatal(err)
        }
        fmt.Printf("Data received: %s", data)
    } else {
        log.Fatal("Unable to establish connection")
    }
}</code>
