Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any Internet site, at times even by 100 percent, based on the content itself. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to lower the overall load on the physical machine and to accelerate the access speed for the website visitors. Anytime a visitor loads a page on a certain Internet site, the browser request is taken care of by the web server and the requested information is delivered as a response. If the Varnish accelerator is activated, it caches the pages that the site visitor opens and in case any of them is loaded once more, it is served by Varnish and not by the web server directly. The performance boost comes from the fact that the accelerator processes the web requests considerably faster than any web server, which leads to much faster browsing speeds for the site visitors. In case any content is updated in the meantime, the cached web pages will also be updated the next time somebody tries to open them.
Varnish in Shared Hosting
Varnish is offered as an optional upgrade with each of our shared plans. You can add it to your website hosting account through the Hepsia hosting Control Panel, which is offered with all shared hosting packages and you will get a really user-friendly GUI, which will grant you complete control over the content caching system. Using 1-click quick-access buttons, you can reboot or discontinue any of the instances, i.e. Varnish will no longer work for a particular website. You can also check an in-depth log file or delete the cache associated with any of the Internet sites. When you add Varnish to your web hosting plan, you will be able to select the maximum amount of system memory that will be available to you for content 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 get a dedicated IP address for the websites that will use Varnish. This will allow you to take full advantage of your sites and to have many satisfied site users.
