Varnish is a web app accelerator platform, which caches data for the sake of faster response times. It’s sometimes called an HTTP reverse proxy as well and it interacts between a web server and an Internet browser. When a site visitor accesses a certain page, its content is requested by the browser, and then the web server handles this browser request and sends back the necessary info. If Varnish is activated for a site, it will cache its pages at the first visit and if the user opens a cached page for a second time, the info will be delivered by the accelerator platform and not by the web server. The increased loading speed is a result of the much faster response speed that Varnish offers compared with any web server software. At the same time, this doesn’t mean that the site visitors will continue seeing the very same content over and over again, as any update on any of the pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Cloud Hosting

Varnish is offered as an optional upgrade with each of our cloud services. You can add it to your hosting account from the Hepsia Control Panel, which is offered with all shared plans and you’ll get a rather simple-to-work-with GUI, which will grant you full control over the content caching system. Using 1-click quick-access buttons, you can reboot or shut down any of the instances, in other words – Varnish will no longer be activated for a specific site. You can also check an exhaustive log or delete the cache for any of the sites. When you add Varnish to your web hosting package, you’ll be able to choose the maximum amount of system memory that will be at your disposal for caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 megabytes and, for best performance, you can assign a dedicated IP to the sites that will use Varnish. This will permit you to get the most out of your websites and to have many pleased users.
