The cache ties to NetworkResourceLoader which lives in the network process.
In principle it would be possible to integrate with the web process side
resource loader too. However I don't want to support multiple
configurations during development.
It would be good if all WK2 ports would eventually switch to using the
network process. The current multitude of configurations makes networking
related code more confusing and less hackable than it needs to be.
