func DrainAndClose ¶

func DrainAndClose(body io.ReadCloser)

DrainAndClose fully drains and then closes the given body.

Go's default http.Transport only reuses an underlying TCP connection (keep-alive) when the response body has been read to completion AND closed. Closing a partially-read body forces a fresh connection on the next request and adds socket churn.

Safe to call with a nil body.
