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.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia hosting Control Panel, you will get the Varnish data caching platform at no additional cost and you’ll exert complete control over it via an incredibly easy-to-work-with GUI – you will be able to start, to discontinue or to restart an instance, to view a detailed log, to clear the cache for any Internet site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you own resource-demanding sites with many visitors, you will notice the tremendously faster web page load times and the less load on the machine. This will become a fact shortly after you start using Varnish, as it will need some time to cache the site content that users browse. You can take full advantage of the platform’s capacity in case the Internet sites that are using it also use a dedicated IP, but owing to the fact that your dedicated server comes with several IPs by default, you will not need to pay anything on top of your monthly fee for the machine itself.
