W3 Cache Cart Updating Issue

Hi,

I am running this site with W3 Cache as it seems to be the fastest plugin to use for this site.

When I click on a product, and add to basket on the product page, then go back to the shop page or any other website page. The basket/cart in the top right does not update.

I have tried excluding shop* and /shopping-cart/ from the cached pages but this does not seem to work.

Any help please as its very frustrating.

The page I need help with: [log in to see the link]
