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