Varnish is a web app accelerator tool, which has been gaining a lot of popularity lately, because it can increase the speed of any website, at times even by 100%, based on the content. This tool is sometimes called a caching HTTP reverse proxy too and is used to lower the overall server load and to accelerate the access speed for the site visitors. Whenever a visitor accesses a page on a specific site, the browser request is taken care of by the web server and the requested content is served as a reply. If the Varnish accelerator is enabled, it caches the pages that the website visitor opens and if any of them is opened for a second time, it’s served by Varnish and not by the server directly. The improvement in the performance is due to the fact that the accelerator processes the browser requests considerably quicker than any web server, which leads to much faster browsing speeds for the users. In case any data is modified in the meantime, the cached pages will also be updated the next time somebody tries to access them.
