Varnish is a website accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the loading speed of any website, at times even by one hundred percent, depending on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to accelerate the browsing speed for the site visitors. Each time a visitor opens a page on a certain Internet site, the web browser request is handled by the web server and the requested data is served as a response. If Varnish is activated, it caches the pages that the website visitor opens and in case any of them is accessed for a second time, it’s delivered by Varnish and not by the server directly. The performance boost comes from the fact that the accelerator handles the browser requests considerably quicker than any web server, which results in much faster browsing speeds for the users. If any content is changed meanwhile, the cached web pages will also be updated the next time someone tries to access them.
Varnish in Shared Website Hosting
Varnish is available as an optional upgrade with each and every Linux shared website hosting package and if you wish to use it, you can add it to your shared web hosting account using the Upgrades menu in your Hepsia Control Panel. There’re two different features that can be upgraded – the number of instances and the system memory. The first one pertains to the number of the websites that you want to use Varnish for, whereas the second, which is available in increments of 32 MB, pertains to the total amount of data that the platform can cache at any particular moment. The Hepsia Control Panel’s simple-to-use GUI will enable you to disable or to reboot any instance, to see elaborate logs or to erase the platform’s cache with just one mouse click. For optimum results, you can employ a dedicated IP address for the sites that will use the platform. With Varnish, your website will load significantly faster, meaning more satisfied website visitors and prospective clients.
