Does Rails 3 provide time based caching?

Question

Hi guys,

I need a timebased caching of certain pages. Cache for certain page should be cleared each 15 minutes. Is that possible?

In http://edgeguides.rubyonrails.org/caching_with_rails.html manual I see that there is only manual cache clear methods, such as expire_page or expire_action.

Regards, Alexey
