Varnish is a web application accelerator platform, which caches content for the sake of faster access. It’s occasionally referred to as an HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor opens a particular page, its content is requested by the Internet browser, and then the web server processes this request and delivers the requested information. If Varnish is activated for a particular website, it will cache its pages on the very first request and in case the user accesses a cached page again, the data will be delivered by the accelerator platform instead of the server. The accelerated speed is a result of the substantially faster response time that Varnish offers compared with any server software. At the same time, this does not mean that the website visitors will keep seeing the very same content again and again, as any modification on any of the web pages is reflected in the content that Varnish stores in its memory.
Varnish in Shared Hosting
Varnish comes as an optional upgrade with all our shared hosting. You can add it to your web hosting account via the Hepsia hosting Control Panel, which is offered with all shared web hosting plans and you will get a very intuitive interface, which will grant you complete control over the caching system. Using 1-click fast-access controls, you can restart or turn off any of the instances, i.e. Varnish will no longer be activated for a given website. You can also view an in-depth system log file or erase the cache associated with any of the sites. When you add Varnish to your hosting package, you will be able to select the maximum amount of system memory that will be available to you for data caching purposes and how many sites will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimum performance, you can set a dedicated IP for the websites that will use Varnish. This will enable you to take full advantage of your sites and to have numerous satisfied site users.
Varnish in VPS Servers
Varnish comes by default with each of the VPS servers offered by us given that the virtual server is ordered with the Hepsia Control Panel, so you can improve the overall performance of your sites with only a few clicks of the mouse. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a lower-end plan, the caching platform will be able to utilize several hundred MB, so even if you’ve got a number of websites, you will notice a significant reduction in the server load and a considerably better webpage loading speed. The Varnish platform will have to work for a while as the visitors navigate the site and as soon as the website content has been cached, you will notice the effects. One of the advantages of employing Varnish is that a lower-end and less pricey VPS package will accomplish the very same job as a more costly one without the caching platform, so not only will your sites perform much better, but you will also save a certain amount of cash.
