// to the same object, and those URLRequestContexts are refcounted independently
// of the owning browser context.
// All methods, except the ctor, are expected to be called on
// the IO thread (unless specifically called out in doc comments).
// TODO(dpranke): Fix dependencies on AppCacheServiceImpl so that we don't have
// to worry about clients calling AppCacheServiceImpl methods.
