Possible duplicate:
DOM expires
If I add some data to the local storage of the browser, does it expire, naturally? I'm going to store some data with local HTML 5 storage, but its nature means it will expire in a few weeks.
So, I am wondering if there is a way to check if a data update is needed? Or just update the data every few weeks.
