How it works
Say, you have 5 different blocks on your homepage:
Newest, Best sellers, On sale, Recently viewed, Similar, and Also bought.
Each time a customer opens the page, the server has to make calculations for all the five blocks and return them to the customer.
The full-page cache allows to save this information into the cache at the first opening of the page. The next time the customer opens the page, all the five blocks are already in the cache. Only one instead of five calls to the server is required. Result: minimum 5 times faster showing the page to the customer.
The add-on uses the Varnish cache technology.
Varnish Cache runs at the backend and caches a copy of each web page served by the web server. When a user requests a cached page, Varnish serves the cached copy instead of requesting the same page again and again from the backend server. It makes the Full Page Cache by Varnish so ideal for the stores with high traffic stores and thousands of products.
From the technical point of view, the procedure is the following
- When a web page visitor opens an HTTP page, their call is processed by a fast NGINX reverse server. It works fast and well.
- NGINX makes a call to Varnish. Varnish checks if the results of the page have been cached.
- If yes, it checks if they are stored in the Cookies Session ID. It means that it is not a guest, but a live visitor in the system, who should always get fresh information without cache.
- If not, the system gets data from the cache and shows it to the customer from Varnish. Otherwise, Varnish delegates the process to the application server.
The application server works as usual: the web server processes the CS-Cart code and returns Varnish results.
Varnish sends the result to NGINX and delivers it to the user’s browser.
- Varnish Cache requires pre-configuration of your server environment.
- Not all servers support Varnish Cache optimization.
- Both the add-on installation and server configuration are included in the price. If any problems on your server are revealed, additional payment will be required.
- The add-on is developed for CS-Cart and CS-Cart Multi-Vendor 4.3.6 and above. If you are using another CS-Cart version, an additional paid modification may be required.
- Only anonymous requests could be placed into the cache. A session will last until the website visitor makes an action and becomes a potential buyer through a POST request, for example:
- adding a product to the cart;
- adding a product to the comparison list;
- logging in to the website;
- performing other actions.
Automatic language detection doesn’t work with the Full Page Cache add-on.
