>+
>+        When cache storage hits quota for a given origin, pipe the request back to NetworkProcess.
>+        No record will be put until the quota request is answered.
>+        The request is sent from CacheStorage::Caches to CacheStorage::Engine and to NetworkProcess.
>+        NetworkProcess then sends it to NetworkProcessProxy.
>+        Currently NetworkProcessProxy just answers by keeping the quota as it is.
>+        In the future, NetworkProcessProxy should make a delegate call to let the app using WebKit
>+        make a decision on the quota. This will allow prompting user to bump it as done for other data.
