Golang: Workaround for too many redirects - "stopped after 10 redirects" error

redirects.go

sourceURL := "http://example.com"

// Resolve URL up to 12 redirects.
client := &http.Client{
	CheckRedirect: func() func(req *http.Request, via []*http.Request) error {
		redirects := 0
		return func(req *http.Request, via []*http.Request) error {
			if redirects > 12 {
				return errors.New("stopped after 12 redirects")
			}
			redirects++
			return nil
		}
	}(),
}

req, err := http.NewRequest("GET", sourceURL, nil)
if err != nil {
	return nil, err
}

resp, err := client.Do(req)
if err != nil {
	return nil, err
}

finalURL = resp.Request.URL.String()
