Varnish is a web app accelerator, which has been gaining a lot in popularity lately, as it can increase the speed of any site, sometimes even by 100 percent, depending on the content. This tool is sometimes referred to as an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to accelerate the browsing speed for the website visitors. Anytime a visitor loads a page on a given site, the browser request is taken care of by the web server and the requested info is delivered as a reply. If Varnish is enabled, it caches the web pages that the site visitor opens and if any of them is loaded once more, it is fetched by Varnish and not by the web server directly. The boost in the performance is due to the fact that the accelerator handles the web requests considerably quicker than any web server, which results in much faster browsing speeds for the website visitors. If any content is changed meanwhile, the cached webpages will also be ‘refreshed’ the next time someone attempts to open them.
Varnish in Shared Hosting
Varnish is offered as an optional upgrade with each Linux shared hosting and if you would like to use it, you can add it to your shared hosting account through the Upgrades menu in your Hepsia hosting Control Panel. There’re two different things that can be upgraded – the number of instances and the memory. The first one refers to the number of the websites that you want to use Varnish for, whereas the second, which comes in increments of 32 MB, displays the maximum amount of data that the platform can store at any given time. Hepsia’s simple-to-use interface will allow you to deactivate or to reboot any instance, to view elaborate system logs or to get rid of the platform’s cache with just a click. For optimal results, you can use a dedicated IP address for the websites that will use the platform. With Varnish, your Internet site will load significantly faster, which means more happy site visitors and potential clients.
