Varnish is a web application accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the speed of any Internet site, at times even by one hundred percent, depending 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 physical server and to accelerate the browsing speed for the site visitors. Whenever a visitor opens a page on a certain Internet site, the browser request is taken care of by the web server and the requested information is sent as a response. If the Varnish accelerator is activated, it caches the pages that the visitor opens and if any of them is opened once again, it’s fetched by Varnish and not by the web server directly. The performance increase is due to the fact that the accelerator handles the browser requests significantly quicker than any web server, which results in much faster browsing speeds for the site visitors. In case any data is edited meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody opens them.

Varnish in Website Hosting

In case you host your sites in a website hosting account with our company, you’ll be able to add Varnish with several clicks from your hosting Control Panel. The caching platform is offered as an optional upgrade with all our shared hosting plans and you can choose how many sites will use it and the total amount of system memory that will be available for the cached content. 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’re not tied directly to each other, so you can decide whether you need a lot of memory for one single large-scale site or less memory for multiple smaller ones. You can make use of the full potential of Varnish if the sites use a dedicated IP address. Using the Control Panel, you can effortlessly start/reboot/cancel an instance, delete the cached data individually for each site that employs Varnish or check an in-depth log file.

Varnish in Semi-dedicated Hosting

Varnish is part of the default service set that you’ll obtain if you choose to host your sites under a semi-dedicated server account. You can configure it for any of your sites via our avant-garde Hepsia Control Panel. The default system memory that the Varnish platform can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform simultaneously. As these two features are not tied to each other, you can use a few instances with the default memory or you can add more memory in increments of 32 MB and use all of it for a single site. The Varnish platform works best if you use a dedicated IP for the websites that utilize its power. Hepsia will offer you an easy means of restarting any instance. Also, you’ll be able to delete the cached files with just one single click of the mouse.

Varnish in Dedicated Web Hosting

You can employ Varnish in order to speed up any site that’s hosted on a dedicated server with our company when the Hepsia hosting Control Panel is installed on the machine. Not only will you get the content caching platform ready to be used at no additional fee, but you will also have complete control over it through Hepsia’s simple-to-work-with graphical interface. It’ll take only one mouse click to start or stop an instance or to clear the cached files associated with any website that’s using the Varnish platform and in case you’re more advanced, you can also see the platform’s logs. Varnish comes with at least three gigabytes of virtual memory for caching purposes, so even if you run a large number of sites on your server and they all use the platform, the improvement in their performance will be observable. You will just have to wait for a while till Varnish caches whatever webpages the site visitors load on their end. The platform performs best when the sites use a dedicated IP, but considering the fact that our servers include three free IP addresses, you’ll have all that you need.
