// This throttle never defers starting the URL request or following redirects,
// no matter on mobile or desktop. If any of the checks for the original URL
// and redirect chain are not complete by the time the response headers are
// available, the request is deferred until all the checks are done. It cancels
// the load if any URLs turn out to be bad.
