Prove that closing http.Response.Body without first draining it prevents http.Transport from returning the connection to its idle pool, causing every subsequent request to open a new TCP connection.

흔히 이렇게 알고 있다

Calling resp.Body.Close() — the pattern shown in every tutorial — is sufficient for http.Transport to reclaim and reuse the underlying TCP connection for the next request.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• When resp.Body.Close() is called without draining the body first, http.Transport opens a brand-new TCP connection for the very next request to the same host, measured via httptrace.GotConnInfo.Reused being false.
• When io.Copy(io.Discard, resp.Body) precedes resp.Body.Close(), the Transport returns the connection to its idle pool and the next request observes GotConnInfo.Reused true, dialling zero new connections.
