updateURLMetrics is a convenience function for pushing metrics. It also handles corner cases for incomplete/invalid request data.

func updateURLMetrics(req *Request, resp *http.Response, err error) {
	url := "none"
	if req.baseURL != nil {

	// Errors can be arbitrary strings. Unbound label cardinality is not suitable for a metric
	// system so we just report them as `<error>`.
	if err != nil {

// Stream formats and executes the request, and offers streaming of the response.
// Returns io.ReadCloser which could be used for streaming of the response, or an error
