Using the new cookie-based sessions

Hi all,

I'm just about to deploy my first big site, and i want to use the new cookie-based sessions, instead of pstore or mysql sessions, as i've read about here: http://dev.rubyonrails.org/changeset/6184

Any tips how i'd do this? What files do i need to copy into my rails app directory?

Thanks a million guys
