// - For a factory created to pass to the renderer for subresource requests from

// - For a factory created for a browser-initiated worker main script request:
//   the ID of the process the worker will run in.
//   TODO(https://crbug.com/986188): We should specify kInvalidUniqueID for this
//   worker main script case like the browser-initiated navigation case.
// - For a factory created to pass to the renderer for subresource requests from
//   the worker: that renderer process's ID.
//
// |frame_tree_node_id| is the ID of the FrameTreeNode where the requests are
// associated.
// - For a factory created for a browser-initiated navigation request, or for a
//   factory created for subresource requests from the frame: that frame's ID.
// - For a factory created for workers (which don't have frames):
//   RenderFrameHost::kNoFrameTreeNodeId.
