Varnish is a web accelerator platform, which caches information for quicker response times. It is occasionally referred to as an HTTP reverse proxy as well and it interacts between a web server and a web browser. When a website visitor opens a certain web page, its content is requested by the web browser, and then the web server handles this browser request and returns the required content. If Varnish is enabled for a particular website, it will cache its pages on the first visit and if the user opens a cached page again, the data will be delivered by the caching platform instead of the server. The boosted speed is a result of the substantially faster response time that Varnish offers as compared to any web server software. Of course, this doesn’t mean that the website visitors will keep being served the exact same content over and over again, because any modification on any of the pages is reflected in the content that Varnish saves in its memory.
Varnish in Shared Website Hosting
In case you host your Internet sites in a shared website hosting account with our company, you’ll be able to activate Varnish with several clicks of the mouse from your Control Panel. The caching platform is available as an optional upgrade with all our hosting packages and you can choose the number of the websites that will use it and the total storage space that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they’re not tied directly to each other, so you can choose if you need a lot of memory for a single large-scale site or less memory for multiple smaller ones. You can use the full potential of Varnish in case the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/remove an instance, delete the cached contents independently for each site which employs Varnish or check an elaborate system log.
