 // 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
 // RefPtr<ResourceFetcher> for their lifetime (and will create one if they
 // are initialized without a LocalFrame), so a Document can keep a ResourceFetcher
 // alive past detach if scripts still reference the Document.
