When network process changes cookie accept policy, it will notify web process about policy change so they have the same
policy. However, in current implementation, web process does not actually updates its policy. If WebCookieCache is
already built with old policy, it keeps using the old policy. This means web process could have a different view of
cookies from network process. For example, if policy is changed from Accept to Never, network process will start
rejecting cookies, while web process will keep accepting them into cache. To avoid this issue, this patch ensures cache
is rebuilt when cookie accept policy changes.
