Overview
As noted in #2287 response body should be read until connection is closed when neither Transfer-Encoding nor Content-Length are specified in HTTP/1.1 (item 7 in https://www.rfc-editor.org/rfc/rfc7230#section-3.3.3).
In order not to break any current tests I added a check for the presence of the
Connection: closeheader (which is not required by the spec).For reference this is how go's standard library is doing it: https://github.com/golang/go/blob/aeb0644bd33e67f24e2411a651ac9ff72ddc96b4/src/net/http/transfer.go#L548
