Well.. in my specific problem I'm building a shop with charon extension but the question applies to other situations.

The user add a product to shopping card, but the browser uses the cache, so the new product on the card in only visible after a reload (refresh) page.

Is there any way to avoid this problem?

Take a look at:www.w3schools.com/asp/prop_expires.asp
