We have a breadcrumb block on our product details page. With multiple category trees directing users to a single product page, the breadcrumb trail should change depending on the category which made the referral.
In our case, if Full Page Cache (
FPC) is disabled -- the Breadcrumbs are dynamic and it works like I described.
FPC enabled, the breadcrumb gets fixed on the initial non-cached page request.
How would I go about getting the breadcrumb block to be dynamic on the product page? It's perfectly fine if it's being cached on category results pages.
