Varnish is a web application accelerator, which has been gaining a lot in popularity in recent years, because it can increase the speed of any website, at times even by one hundred percent, based on the content. This tool is sometimes called an HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to accelerate the browsing speed for the website visitors. Every time a visitor loads a page on a certain website, the web browser request is taken care of by the web server and the requested info is delivered as a response. If Varnish is activated, it caches the pages that the site visitor browses and in case any of them is opened for a second time, it’s fetched by Varnish and not by the web server directly. The performance improvement is due to the fact that the accelerator handles the web requests significantly faster than any web server, which leads to much faster browsing speeds for the site visitors. If any data is updated in the meantime, the cached web pages will also be updated the next time somebody opens them.
Varnish in Website Hosting
Varnish is available as an optional upgrade with each of our Linux website hosting packages. You can add it to your account through the Hepsia hosting Control Panel, which comes with all shared plans and you’ll get a truly simple-to-work-with interface, which will grant you full control over the data caching system. Using one-click fast-access controls, you can restart or cancel any of the instances, in other words – Varnish will no longer work for a particular site. You can also view a detailed system log or clear the cache associated with any of the Internet sites. When you add Varnish to your hosting plan, you will be able to choose the total amount of memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for maximum performance, you can get 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 a lot of happy site visitors.
