Varnish is a content caching platform, which is sometimes referred to as an HTTP reverse proxy. It’s a web accelerator tool that can boost the loading speed of a site by up to 1000 percent, based on its content. Every time a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor opens it again. Thus, the web browser request from the visitor is not processed by the web server and the page will load substantially faster, as the Varnish platform can serve content many times faster than any web server software. The end result is a significantly faster loading site, which leads to an immensely improved website browsing experience. In case any of the cached web pages is updated on the actual site, the information that Varnish keeps in its system memory is ‘refreshed’ as well, so the users won’t see old information.

Varnish in Shared Web Hosting

In case you host your sites in a shared web hosting account with us, you will be able to add Varnish with a few clicks of the mouse through your hosting Control Panel. The platform is offered as an optional upgrade with all our shared hosting packages and you can select how many websites 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 amount of system memory and the number of instances and they aren’t linked directly to each other, so you can decide if you want a lot of memory for a single large site or less memory for several smaller ones. You can unlock the full potential of Varnish if the sites use a dedicated IP. Using the Control Panel, you can easily start/reboot/shut down an instance, delete the cached files individually for each site that employs the Varnish platform or check an exhaustive log file.

Varnish in Semi-dedicated Servers

The Varnish data caching platform is included in the standard service set that you’ll acquire when you choose to host your Internet sites under a semi-dedicated server account. You can configure it for any of your websites through our advanced Hepsia Control Panel. The default amount of memory that Varnish can use to cache content is 64 megabytes, but in case you decide that you need more, you can upgrade this memory 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 at the same time. Since these two features are not linked to each other, you can use several Internet sites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single Internet site. The Varnish caching platform performs best if you set a dedicated IP address for the websites that utilize its power. Hepsia will provide you with an easy means of restarting any instance. On top of that, you’ll be able to delete the cached contents with just one single click.

Varnish in Dedicated Servers

You can use Varnish to boost the loading speed of any site that is hosted on a dedicated server from us if the Hepsia hosting Control Panel is pre-installed on it. Not only will you get the data caching platform ready to be used at no extra fee, but you’ll also exert full control over it via Hepsia’s user-friendly graphical interface. It’ll take only one single click of the mouse to start or delete an instance or to clear the cache associated with any Internet site that is using the Varnish platform and if you are more sophisticated, you can also see the platform’s logs. Varnish comes with no less than 3 gigabytes of virtual memory for web content caching purposes, so even if you run a vast number of websites on your dedicated server and they all use the Varnish platform, the difference in their performance will be distinguishable. You’ll just have to wait for a little while till Varnish caches whatever web pages the site visitors browse on their end. The Varnish platform performs best when the Internet sites use a dedicated IP, but considering the fact that our dedicated servers come with three free IPs, you will have all that you need.
