Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any website, at times even by 100 percent, depending on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical server and to boost the browsing speed for the site visitors. Whenever a visitor opens a page on a certain Internet site, the web browser request is taken care of by the web server and the requested info is delivered as a reply. If Varnish is activated, it caches the web pages that the visitor browses and if any of them is opened once again, it’s fetched by Varnish and not by the server directly. The increase in the performance is due to the fact that the accelerator processes the web requests substantially faster than any web server, which results in much faster browsing speeds for the visitors. In case any data is updated meanwhile, the cached web pages will also be updated the next time someone tries to open them.
Varnish in Shared Web Hosting
Varnish is available as an optional upgrade with all our shared web hosting. You can add it to your web hosting account through the Hepsia hosting Control Panel, which is available with all shared hosting packages and you will get a very easy-to-work-with graphical interface, which will grant you complete control over the caching system. Using one-click fast-access buttons, you can reboot or deactivate any of the instances, in other words – Varnish will no longer work for a given website. You can also see a comprehensive system log or delete the cache associated with any of the Internet sites. When you add Varnish to your shared hosting plan, you’ll be able to select the maximum amount of memory that will be at your disposal for caching purposes and how many sites will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimal performance, you can allocate a dedicated IP to the sites that will use Varnish. This will permit you to get the most out of your websites and to have numerous happy users.
