Varnish is a website accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, at times even by 100 percent, depending on the content itself. This tool is occasionally called an HTTP reverse proxy too and is used to reduce the overall load on the physical server and to increase the browsing speed for the site visitors. Every time a visitor opens a page on a specific Internet site, the web browser request is taken care of by the web server and the requested information is delivered as a reply. If the Varnish accelerator is activated, it caches the pages that the website visitor opens and if any of them is opened for a second time, it is delivered by Varnish and not by the server directly. The increase in the overall performance comes from the fact that the accelerator handles the browser requests significantly faster than any web server, which leads to much faster browsing speeds for the users. In case any data is changed meanwhile, the cached pages will also be updated the next time someone accesses them.

Varnish in Shared Hosting

If you host your websites in a shared hosting account with our company, you’ll be able to add Varnish with a few mouse clicks through your hosting Control Panel. The data caching platform is offered as an upgrade with all our shared plans and you can select the number of the sites that will use it and the total amount of system memory that will be available for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they are not directly tied to each other, so you can choose whether you want a lot of memory for one single large-size site or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish if the websites use a dedicated IP. With the Control Panel, you can quickly start/restart/remove an instance, clear the cached data individually for each site which uses the Varnish platform or view a detailed log.
