Learn precisely what Varnish is. Know a lot more about web accelerators and their role.
Varnish is a web application accelerator platform, which caches information for the sake of quicker response times. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a site visitor accesses a particular page, the content is requested by the browser, and then the web server processes this browser request and sends back the necessary info. If Varnish is enabled for a site, it will cache its pages at the very first visit and if the visitor accesses a cached page once again, the info will be delivered by the accelerator platform and not by the web server. The accelerated speed is an end result of the considerably faster response time that Varnish offers as compared with any server software. Of course, this does not mean that the users will continue being served the exact same content again and again, as any change on any of the web pages is reflected in the content that the Varnish platform caches in its memory.
