Learn exactly what Varnish is. Discover much more about web accelerators and their purpose.
Varnish is a web app accelerator platform, which caches info for the sake of quicker response times. It’s sometimes referred to as a caching HTTP reverse proxy too and it works between a web server and a browser. When a site visitor loads a certain web page, the content is requested by the Internet browser, and then the server processes this browser request and returns the required content. If Varnish is enabled for a website, it will cache the pages on the first visit and in case the visitor opens a cached page once more, the info will be delivered by the accelerator platform instead of the server. The increased load speed is an end result of the considerably faster response speed that the Varnish platform offers compared to any server software. At the same time, this doesn’t mean that the users will continue seeing the exact same content over and over again, because any modification on any of the web pages is reflected in the content that the Varnish platform stores in its memory.
