Varnish is a website accelerator, which has been gaining a lot of popularity lately, as it can increase the loading speed of any website, at times even by 100 percent, depending on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to reduce the overall server load and to boost the access speed for the website visitors. Each time a visitor accesses a page on a given Internet site, the browser request is taken care of by the web server and the requested data is delivered as a response. If the Varnish accelerator is activated, it caches the pages that the site visitor opens and if any of them is accessed once again, it is delivered by Varnish and not by the web server directly. The performance improvement is due to the fact that the accelerator handles the web requests tremendously faster than any web server, which results in much faster browsing speeds for the website visitors. If any data is changed meanwhile, the cached pages will also be updated the next time somebody opens them.
Varnish in Shared Web Hosting
Varnish is offered as an optional upgrade with each and every Linux shared web hosting package and if you would like to use it, you can add it to your account via the Upgrades menu in your Hepsia Control Panel. There are two different features that can be upgraded – the instances and the memory. The first one refers to the number of the Internet sites that you’d like to use Varnish for and the second one, which comes in increments of 32 MB, refers to the maximum amount of data that the data caching platform can store at any given moment. Hepsia’s user-friendly GUI will allow you to terminate or to restart any instance, to check detailed logs or to clear the platform’s cache with just click of the mouse. For optimal results, you can use a dedicated IP address for the Internet sites that will use the platform. With Varnish, your website will open much faster, which means more satisfied users and prospective clients.
