Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the speed of any website, at times even by 100 percent, depending on the content itself. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall server load and to increase the browsing speed for the website visitors. Each time a visitor accesses a page on a particular site, the web browser request is taken care of by the web server and the requested information is sent as a reply. If the Varnish accelerator is activated, it caches the pages that the website visitor browses and in case any of them is loaded once more, it’s delivered by Varnish and not by the server directly. The increase in the overall performance is due to the fact that the accelerator handles the browser requests considerably quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is modified in the meantime, the cached web pages will also be updated the next time somebody opens them.
