Codeigniter caching

[quote author="surfgatinho" date="1219624584"]The problem with using the Codeigniter caching is it caches the whole page (or at least that's what I think)
If you are running an ecommerce app this isn't going to work well with the cart or logged in views[/quote]

Ah, good point, now I know why the # of items in cart at the top of the page always said "1". I think I can resolve that by putting that item of the page in a little iframe...The cart is stored in the database and referred to throughout shopping and checkout with the CI session id, so that is holding up nicely even with the caching...
