// ResourceFetcherProperties consists of properties of the global context (e.g.,
// Frame, Worker) necessary to fetch resources. FetchClientSettingsObject
// implementing https://html.spec.whatwg.org/C/webappapis.html#settings-object
// is one such example.
//
// This class consists of pure virtual getters. Do not put operations. Do not
// put getters for a specific request such as
// GetCachePolicy(const ResourceRequest&, ResourceType). Do not put a function
// with default implementation.
//
// Storing a non-null ResourceFetcherProperties in an object that can be valid
// after the associated ResourceFetcher is detached is dangerous. Use
// DetachedResourceFetcherProperties below.
//
// The distinction between FetchClientSettingsObject and
// ResourceFetcherProperties is sometimes ambiguous. Put a property in
// FetchClientSettingsObject when the property is clearly defined in the spec.
// Otherwise, put it to this class.

    : public GarbageCollected<ResourceFetcherProperties> { … };

// A delegating ResourceFetcherProperties subclass which can be retained
