// Class to store information about network stack requests based on the context
// in which they are made. It provides NetworkIsolationKeys, used to shard the
// HTTP cache, NetworkAnonymizationKeys, used to shard other network state, and
// SiteForCookies, used determine when to send same site cookies. The
// IsolationInfo is typically the same for all subresource requests made in the
// context of the same frame, but may be different for different frames within a
// page. The IsolationInfo associated with requests for frames may change as
// redirects are followed, and this class also contains the logic on how to do
// that.
//
// TODO(crbug.com/40093296): The SiteForCookies logic in this class is currently
// unused, but will eventually replace the logic in URLRequest/RedirectInfo for
// tracking and updating that value.
