Varnish is a web application accelerator, which has been gaining a lot in popularity lately, as it can increase the speed of any website, at times even by 100 percent, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to decrease the overall load on the server and to enhance the access speed for the site visitors. Anytime a visitor opens a page on a specific Internet site, the web browser request is handled by the web server and the requested data is served as a response. If the Varnish accelerator is activated, it caches the pages that the visitor browses and in case any of them is accessed once more, it is fetched by Varnish and not by the server directly. The increase 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. If any content is changed in the meantime, the cached pages will also be ‘refreshed’ the next time someone opens them.
Varnish in Shared Web Hosting
Varnish is offered as an optional upgrade with each of our shared web hosting plans. You can add it to your account from the Hepsia Control Panel, which comes with all shared web hosting plans and you will get a quite easy-to-use GUI, which will grant you complete control over the data caching system. Using one-click fast-access controls, you can restart or turn off any of the instances, i.e. Varnish will no longer be enabled for a particular Internet site. You can also see an elaborate system log or erase the cache for any of the websites. When you add Varnish to your hosting plan, you’ll be able to choose the total amount of system memory that will be available to you for data caching purposes and how many sites will use Varnish. You can always add more memory in increments of 32 megabytes and, for optimum performance, you can assign a dedicated IP address to the websites that will use Varnish. This will permit you to get the most out of your Internet sites and to have plenty of happy website visitors.
