Varnish is a web app accelerator, which has been gaining a lot of popularity lately, because it can increase the loading speed of any Internet site, at times even by 100 percent, depending on the content. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to decrease the overall load on the server and to enhance the browsing speed for the site visitors. Anytime a visitor accesses a page on a specific site, the web browser request is processed by the web server and the requested info is sent as a reply. If the Varnish accelerator is activated, it caches the web pages that the website visitor browses and if any of them is opened once more, it’s served by Varnish and not by the web server directly. The performance improvement comes from the fact that the accelerator handles the browser requests substantially faster than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is changed in the meantime, the cached pages will also be updated the next time someone accesses them.
