Learn just what Varnish is. Discover much more about web accelerators and their goal.
Varnish is a web app accelerator, which has been gaining a lot of popularity lately, as it can increase the speed of any website, sometimes even by 100%, based on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to decrease the overall load on the server and to accelerate the access speed for the website visitors. Anytime a visitor accesses a page on a specific site, the web browser request is handled by the web server and the requested data is sent as a reply. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and if any of them is opened for a second time, it is served by Varnish and not by the web server directly. The boost in the overall performance is due to the fact that the accelerator handles the browser requests considerably quicker than any web server, which leads to much faster browsing speeds for the website visitors. If any content is updated in the meantime, the cached webpages will also be updated the next time somebody accesses them.
Varnish in Website Hosting
Varnish is offered 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 is available with all shared packages and you’ll get a truly simple-to-use GUI, which will grant you complete control over the content caching system. Using one-click fast-access controls, you can restart or delete any of the instances, in other words – Varnish will no longer be activated for a certain website. You can also see an elaborate log file or clear the cache associated with any of the sites. When you add Varnish to your hosting plan, you will be able to select the total amount of system memory that will be at your disposal for data caching purposes and how many sites will use Varnish. You can always get more memory in increments of 32 MB and, for top performance, you can assign a dedicated IP to the websites that will use Varnish. This will permit you to get the most out of your Internet sites and to have numerous satisfied website users.
