Varnish is a web accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any Internet site, at times even by 100%, based on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall load on the server and to accelerate the browsing speed for the website visitors. Anytime a visitor loads a page on a certain site, the browser request is handled by the web server and the requested info is delivered as a response. If the Varnish accelerator is enabled, it caches the web pages that the visitor browses and if any of them is loaded again, it is fetched by Varnish and not by the web server directly. The improvement in the overall performance comes from the fact that the accelerator handles the browser requests tremendously faster than any web server, which leads to much faster browsing speeds for the visitors. In case any content is edited meanwhile, the cached pages will also be updated the next time somebody accesses them.

Varnish in Shared Hosting

If you host your Internet sites under a shared hosting account with our company, you will be able to add Varnish with a couple of mouse clicks via your Control Panel. The caching platform is available as an optional upgrade with all our web hosting packages and you can choose the number of the sites that will use it and the maximum amount of system memory that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they are not linked directly to each other, so you can decide if you want lots of memory for a single large-sized website or less memory for several smaller ones. You can unlock the full potential of the Varnish platform in case the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/remove an instance, delete the cached contents individually for each site which uses Varnish or see an in-depth log file.
