Nginx is now enabled by default for all packages as a reverse proxy cache. Normally, the benefits of caching are visible through an increase in the general speed and availability of your sites via caching. This works by saving a copy of site content, then returning this copy to the user directly. Removing the need to request and generate the content from the origin server every time a user visits a site. This is a much more efficient way of handling requests, especially on busy sites.
However, on occasion, caching will need to be disabled or cleared.
One such occasion is during the active development of a site. You might need changes to appear immediately, because of how caching works it might be best to disable the cache entirely for the duration of development.
This guide outlines how to do this from your cPanel control panel, so you must first log in to cPanel.
