did you consider putting this on OfflinePageClientPolicy as an instance method?

[romax, 2016/05/03 00:29:24]

no... I dont think it's useful to be a method in the class... since the enum in
the ClientPolicy.LifetimePolicy would tell if it's a temporary one. But if
you're referring to a validation method, it would be useful. However it wouldn't
be necessary until we remove the hand written policies.

+  // Check if policy has a expire period > 0 or a limited number
+  // of pages allowed.
+  return (policy.lifetime_policy.page_limit > kUnlimitedPages ||
+          !policy.lifetime_policy.expire_period.is_zero());
+}
+
+}  // namespace
