// This class is an implementation of mojom::URLLoaderFactory that
// creates a mojom::URLLoader.
// A URLLoaderFactory has a pointer to ResourceSchedulerClient. A
// ResourceSchedulerClient is associated with cloned
// NetworkServiceURLLoaderFactories. Roughly one URLLoaderFactory
// is created for one frame in render process, so it means ResourceScheduler
// works on each frame.
// A URLLoaderFactory can be created with null ResourceSchedulerClient, in which
// case requests constructed by the factory will not be throttled.
// Note that the CORS related part is implemented in CorsURLLoader[Factory]
// and NetworkContext::CreateURLLoaderFactory returns a CorsURLLoaderFactory,
// instead of a URLLoaderFactory.
