Varnish is a web application accelerator platform, which caches data for the sake of quicker access. It’s occasionally referred to as an HTTP reverse proxy as well and it works between a web server and a browser. When a site visitor accesses a particular page, the content is requested by the web browser, and then the server handles this browser request and returns the required info. If Varnish is activated for a specific website, it will cache the pages on the first visit and if the user visits a cached page for a second time, the information will be delivered by the accelerator platform and not by the server. The increased loading speed is an end result of the considerably faster response speed that the Varnish platform offers compared to any web server software. Of course, this doesn’t mean that the site visitors will continue seeing the same content over and over again, as any change on any of the pages is reflected in the content that the Varnish platform saves in its memory.
