Varnish is a web accelerator, which has been gaining a lot in popularity in recent years, because it can increase the loading speed of any Internet site, sometimes even by one hundred percent, depending on the content. This tool is sometimes called a caching HTTP reverse proxy too and is used to lower the overall load on the physical server and to accelerate the access speed for the website visitors. Each time a visitor loads a page on a particular site, the web browser request is handled by the web server and the requested information is returned as a reply. If the Varnish accelerator is activated, it caches the web pages that the site visitor browses and if any of them is accessed for a second time, it is fetched by Varnish and not by the server directly. The boost in the overall performance comes from the fact that the accelerator handles the web requests considerably faster than any web server, which results in much faster browsing speeds for the users. If any content is updated meanwhile, the cached web pages will also be updated the next time someone attempts to access them.

Varnish in Web Hosting

Varnish is offered as an optional upgrade with each web hosting plan and if you’d like to use it, you can add it to your shared hosting account through the Upgrades section in your Hepsia Control Panel. There are two separate features that can be upgraded – the number of instances and the memory. The first one refers to the number of the Internet sites that you wish to employ Varnish for and the second one, which is offered in increments of 32 MB, refers to the maximum amount of content that the content caching platform can store at any given moment. The Hepsia Control Panel’s simple-to-work-with GUI will allow you to switch off or to restart any instance, to check exhaustive logs or to erase the platform’s cache with just click of the mouse. For optimal results, you can use a dedicated IP for the sites that will use the caching platform. With Varnish, your site will load significantly faster, which means more pleased site users and potential customers.
