   *  - "Lax": the cookie is omitted when the subject URL is an embedded resource. It is sent for
   *    potentially-destructive navigation. This is the default value.

   * `ConcurrentModificationException`, but if new responses are added while iterating, their URLs

   * The iterator supports [MutableIterator.remove]. Removing a URL from the iterator evicts the
