Redirects with schema changes: Too many redirects detected when doing the request

[gabrielperezs]

For the testing you can use the url http://www.reddit.com/static/button/button1.js, if you do a simple curl to this url will return a 301 code with a new url over https:

HTTP/1.1 301 Moved Permanently
Retry-After: 0
Location: https://www.reddit.com/static/button/button1.js
Content-Length: 0
...

But using the fasthttp.HostClient will return an error "301 too many redirects detected when doing the request"

Code example to reproduce it.

package main

import (
	"fmt"
	"net/url"
	"time"

	"github.com/valyala/fasthttp"
)

var (
	destUrl = "http://www.reddit.com/static/button/button1.js"
)

func main() {

	u, err := url.Parse(destUrl)
	if err != nil {
		fmt.Println(err)
		return
	}

	var reqClient *fasthttp.HostClient
	port := 80

	reqClient = &fasthttp.HostClient{
		Addr: fmt.Sprintf("%s:%d", string(u.Host), port),
	}

	statusCode, body, err := reqClient.GetTimeout(nil, destUrl, 4000*time.Millisecond)
	if err != nil {
		fmt.Println(statusCode, err)
		return
	}

	fmt.Println(statusCode, string(body))
}
