Varnish is a web app accelerator platform, which caches content 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 its users. When a site visitor accesses a given web page, the content is requested by the browser, and then the server handles this request and sends back the required data. If Varnish is activated for a particular website, it will cache the pages at the very first request and in case the visitor accesses a cached page once more, the info will be delivered by the caching platform instead of the server. The increased speed is a result of the significantly faster response speed that the Varnish platform offers compared with any web server software. Of course, this does not mean that the users will keep being served the same content again and again, because any modification on any of the pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Hosting
Varnish is available as an optional upgrade with each of our Linux hosting packages. You can add it to your account through the Hepsia Control Panel, which comes with all shared plans and you’ll get a really easy-to-work-with interface, which will grant you complete control over the content caching platform. Using one-click fast-access buttons, you can reboot or cancel any of the instances, i.e. Varnish will no longer work for a particular site. You can also see a detailed log or erase the cache for any of the Internet sites. When you add Varnish to your shared hosting plan, you will be able to choose the maximum amount of memory that will be at your disposal for caching purposes and how many sites will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimal performance, you can set a dedicated IP address for the sites that will use Varnish. This will enable you to take full advantage of your Internet sites and to have a lot of happy site users.
