why would you look at the old blogpost for the new behavior?
It's all web pages, regardless of classification or redirects. The new webkit blog post is quite clear:
> Now ITP has aligned the remaining script-writable storage forms with the existing client-side cookie restriction, deleting all of a website’s script-writable storage after seven days of Safari use without user interaction on the site
Or straight from the ITP lead's twitter:
> Fifth, all script-writeable storage is now aligned with the 7-day expiry Safari already has for client-side cookies.
(with follow up replies on what resets the seven day clock)
