Caching of dynamic pages
We are developing a Shopware shop for a new customer. One of the features is dynamic pricing (customer-based prices) where customers are shown personalized prices that are loaded from an api. We had this working, deployed it to a test environment and noticed it didn't work because the cache is enabled on category and product detail pages when the production mode is enabled.
We load the prices using a subscriber that is based on '\Shopware\Core\Content\Product\Subscriber\ProductSubscriber'. But because of the caching in classes like '\Shopware\Core\Content\Category\SalesChannel\CachedCategoryRoute' the 'SalesChannelEntityLoadedEvent' is never fired and the original Shopware prices are cached as part of the page content.
When a customer is logged in you generally want to display personalized content, whether it's pricing, notifications, product suggestions, a personalized banner or special prices. That's why pages like that are usually not cached in systems like Magento, for example, when a customer is logged in.
Can you tell us if there's any other way to accomplish personalized/dynamic prices? We liked this approach because it ensures the right prices are always loaded on the products, whether it's on a shop page or when a customer adds a product to his/her cart.
