go1.8 windows/amd64 ### What did you do? I run this simple program: ``` golang package main import ( "fmt" "net/http" ) func main() { resp, err := http.Head("http://t.co/2LhlOo2EtX") if err != nil { fmt.Println(err) return } resp.Body.Close() fmt.Println(resp.Request.URL.String()) } ``` ### What did you expect to see? A single line with unshorten t.co URL: ``` https://golang.org/dl/ ``` ### What did you see instead? Some log message before expected output: ``` 2017/04/08 16:39:00 Unsolicited response received on idle HTTP channel starting with "0\r\n\r\n"; err=<nil> https://golang.org/dl/ ```
