A Simple Way To Configure The Full-Page Cache In Magento 2 Admin Panel

To display category, product, and CMS pages quickly, Magento Open Source uses full-page caching on the server. Full-page caching enhance response time and reduces the load on the server, Magento Open Source uses full-page caching on the server. Without caching, each page might need to run blocks of code and retrieve information from the database. However, with full-page caching enabled, a fully-generated page can be read directly from the cache.

We recommend using Varnish only in a production environment.

The system can use the cached content to process the requests from similar types of visits. Pages shown to a casual visitor might differ from those shown to a customer. For the purposes of caching, there are 3 types of visit:

Non-sessioned: During a non-sessioned visit, a customer views pages but does not interact with the store. The system caches the content of each page viewed and serves them to other non-sessioned customers.

Sessioned: During a sessioned visit, customers who interact with the store through activities such as comparing products or adding products to the shopping cart, are assigned a session ID. Cached pages that are generated during the session are used only by that customer during the session.

Customer: Customer sessions are created for those who have registered for an account while logged in to their accounts. During the session, special offers, promotions, and prices that are based on the customer group to which they are assigned can be present to them.

For technical information, see Configure and Use Varnish and Use Redis for the Magento page and default cache in the developer documentation.
