Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, as it can increase the speed of any website, at times even by one hundred percent, based on the content. This tool is occasionally called an HTTP reverse proxy as well and is used to decrease the overall server load and to improve the access speed for the website visitors. Every time a visitor accesses a page on a certain website, the browser request is handled by the web server and the requested data is delivered as a response. If Varnish is activated, it caches the web pages that the website visitor opens and in case any of them is opened again, it’s served by Varnish and not by the server directly. The performance boost comes from the fact that the accelerator handles the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any content is edited meanwhile, the cached pages will also be ‘refreshed’ the next time someone attempts to open them.
Varnish in Shared Web Hosting
Varnish comes as an optional upgrade with each and every shared web hosting and if you want to use it, you can add it to your shared website hosting account using the Upgrades menu in your Hepsia Control Panel. There’re two different things that can be upgraded – the instances and the memory. The first one pertains to the number of the sites that you’d like to employ Varnish for, whereas the second, which comes in increments of 32 megabytes, pertains to the total amount of data that the platform can cache at any given time. Hepsia’s easy-to-use graphical interface will permit you to discontinue or to restart any instance, to view comprehensive system logs or to delete the platform’s cache with just one mouse click. For optimum results, you can employ a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your Internet site will load significantly faster, meaning more satisfied website users and prospective clients.
