Varnish is a website accelerator platform, which caches content for the sake of faster access. It is occasionally called an HTTP reverse proxy too and it interacts between a web server and a web browser. When a site visitor opens a specific web page, the content is requested by the browser, and then the web server processes this browser request and sends back the required content. If Varnish is enabled for a certain website, it will cache the pages on the very first request and in case the visitor opens a cached page for a second time, the information will be delivered by the accelerator platform and not by the web server. The improved load speed is a result of the substantially faster response time that the Varnish platform offers compared with any server software. Of course, this does not mean that the visitors will keep seeing the exact same content again and again, as any modification on any of the pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Shared Web Hosting
Varnish comes as an optional upgrade with each of our shared web hosting. You can add it to your hosting account via the Hepsia Control Panel, which is offered with all shared hosting packages and you will get a rather easy-to-use GUI, which will give you complete control over the caching platform. Using 1-click fast-access controls, you can restart or disable any of the instances, i.e. Varnish will no longer be activated for a certain site. You can also see a detailed system log file or erase the cache for any of the Internet sites. When you add Varnish to your web hosting package, you will be able to choose the maximum amount of system memory that will be at your disposal for data caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 megabytes and, for top performance, you can set a dedicated IP address for the websites that will use Varnish. This will allow you to get the most out of your Internet sites and to have plenty of satisfied users.
