Discover Varnish, learn more details on web accelerators and discover just what it is that they do.
Varnish is a website accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any site, sometimes even by one hundred percent, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to enhance the access speed for the site visitors. Anytime a visitor opens a page on a specific website, the web browser request is handled by the web server and the requested info is served as a reply. If Varnish is enabled, it caches the web pages that the visitor browses and in case any of them is loaded again, it’s served by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator processes the browser requests substantially faster than any web server, which results in much faster browsing speeds for the site visitors. If any data is edited in the meantime, the cached webpages will also be updated the next time somebody tries to open them.
