Full Page Caching (FPC) for Umbraco websites.
Full Page Caching (often abbreviated as FPC) is a caching method that allows you to store static content from a web page in your cache.
With FPC you can cache the static content of your site, which means that you no longer have to make various calculations during the retrieval of the page. After all, the content is not changed and can therefore be used by everyone. By storing this content in your cache, a page can be built faster.
The first time the Umbrao application is started, cache pages will be created for each specific page. On the first visit you will immediately notice the speed gains caused by FPC, because all calculations have been performed and saved for the first time. Everytime you make edit to your Umbraco pages the cache will be regenerated.
When the page is visited after the data has been cached, the static content of the website is displayed on the page almost immediately. After all, the calculations no longer need to be made, because the outcome is cached. This applies to every visitor who visits the page.
The page loads super fast with every new visit. This is because the static contact is cached. The page is cached and therefore does not need to be recalculated.
