Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, as it can increase the load speed of any website, at times even by one hundred percent, based on the content itself. This tool is occasionally referred to as an HTTP reverse proxy too and is used to decrease the overall load on the physical server and to increase the browsing speed for the site visitors. Anytime a visitor loads a page on a specific site, the browser request is processed by the web server and the requested content is returned as a response. If the Varnish accelerator is activated, it caches the pages that the website visitor opens and in case any of them is opened once again, it’s served by Varnish and not by the server directly. The boost in the performance comes from the fact that the accelerator processes the web requests tremendously faster than any web server, which leads to much faster browsing speeds for the website visitors. In case any content is modified meanwhile, the cached web pages will also be ‘refreshed’ the next time someone opens them.
