Varnish is a web accelerator platform, which caches information for the sake of quicker response times. It’s sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and a browser. When a site visitor accesses a given web page, the content is requested by the Internet browser, and then the server processes this request and returns the required info. If Varnish is enabled for a certain website, it will cache the pages at the very first request and if the visitor opens a cached page again, the data will be delivered by the accelerator platform instead of the web server. The accelerated loading speed is a result of the much faster response speed that Varnish offers as compared to any web server software. Of course, this does not mean that the site visitors will keep being served the very same content again and again, since any change on any of the web pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Cloud Web Hosting

In case you host your Internet sites in a cloud web hosting account with us, you’ll be able to activate Varnish with a few clicks from your hosting Control Panel. The caching platform is available as an optional upgrade with all our shared hosting plans and you can select the number of the websites that will use it and the maximum storage space that will be available for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they are not directly linked to each other, so you can choose if you need lots of memory for one single large site or less memory for several smaller ones. You can unleash the full potential of the Varnish caching platform in case the sites use a dedicated IP. Using the hosting Control Panel, you can swiftly start/restart/disable an instance, delete the cached data independently for each site that employs the Varnish platform or view an exhaustive log.
