// Holds the internal state of a ChildURLLoaderFactoryBundle in a form that is

//
// |pending_subresource_proxying_loader_factory| is used only by the frames who
// may send prefetch requests by <link rel="prefetch"> tags, or send fetch
// requests with {browsingTopics: true} flag. For prefetch, this loader factory
// allows prefetch loading to be done by the browser process (therefore less
// memory pressure), and also adds special handling for Signed Exchanges (SXG)
// when the flag is enabled. TODO(crbug/803776): deprecate this once SXG
// specific code is moved into Network Service unless we see huge memory benefit
// for doing this. For topics, this loader factory allows intercepting and
// processing the topics headers in the browser process.
//
// |pending_keep_alive_loader_factory| is used only by the frames who may send
// fetch requests with {keepalive: true} flag. The loader factory allows
// keepalive request handling to be proxied via the browser process. The browser
// may forward the response back if the request initiator frame is still alive.
// It is only set if `blink::features::kKeepAliveInBrowserMigration` is true.
// See also crbug.com/1356128 and

//
// |pending_fetch_later_loader_factory| is used only by the frames who may send
// fetchLater() requests. The loader factory allows such requests to be proxied
// via the browser process.
// It is only set if `blink::features::kFetchLaterAPI` is true.
// See also crbug.com/1465781 and
