Varnish is a web app accelerator, which has been gaining a lot in popularity lately, as it can increase the load speed of any website, sometimes even by 100%, depending on the content itself. This tool is occasionally called an HTTP reverse proxy too and is used to decrease the overall load on the physical server and to boost the access speed for the site visitors. Every time a visitor accesses a page on a specific website, the web browser request is taken care of by the web server and the requested data is sent as a response. If Varnish is activated, it caches the web pages that the website visitor browses and in case any of them is opened again, it’s fetched by Varnish and not by the server directly. The improvement in the overall performance comes from the fact that the accelerator processes the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is modified in the meantime, the cached webpages will also be updated the next time someone opens them.
Varnish in Web Hosting
We offer Varnish as an optional upgrade with each and every web hosting and if you would like to use it, you can add it to your hosting account through the Upgrades menu in your Hepsia hosting Control Panel. There’re two separate features that can be upgraded – the instances and the system memory. The first one refers to the number of the websites that you would like to employ Varnish for, whereas the second, which is available in increments of 32 megabytes, displays the total amount of data that the platform can cache at any given moment. Hepsia’s simple-to-use graphical interface will allow you to switch off or to restart any instance, to check detailed 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 platform. With Varnish, your Internet site will load substantially faster, meaning more satisfied website users and prospective customers.
