Varnish is a web accelerator platform, which caches content for the sake of faster response times. It is occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a website visitor accesses a specific web page, its content is requested by the web browser, and then the server processes this browser request and sends back the required content. If Varnish is enabled for a site, it will cache its pages at the first visit and in case the visitor accesses a cached page once again, the info will be delivered by the accelerator platform instead of the web server. The improved speed is a result of the considerably faster response time that the Varnish platform offers as compared with any web server software. At the same time, this doesn’t mean that the visitors will continue being served the very same content over and over again, since any change on any of the web pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Shared Hosting
Varnish is offered as an optional upgrade with each of our shared hosting. You can add it to your account from the Hepsia Control Panel, which is offered with all shared hosting plans and you will get a very easy-to-work-with interface, which will give you complete control over the caching platform. Using 1-click quick-access buttons, you can restart or turn off any of the instances, i.e. Varnish will no longer be enabled for a certain site. You can also view an exhaustive log or clear the cache for any of the sites. When you add Varnish to your hosting plan, you’ll be able to select the maximum amount of memory that will be available to you for data caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 MB and, for best performance, you can set a dedicated IP for the sites that will use Varnish. This will permit you to take full advantage of your sites and to have numerous pleased site users.
