 // The ResourceFetcher provides a per-context interface to the MemoryCache and
 // enforces a bunch of security checks and rules for resource revalidation. Its
 // lifetime is roughly per-DocumentLoader, in that it is generally created in
 // the DocumentLoader constructor and loses its ability to generate network
 // requests when the DocumentLoader is destroyed. Documents also hold a pointer
 // to ResourceFetcher for their lifetime (and will create one if they are
 // initialized without a LocalFrame), so a Document can keep a ResourceFetcher
