Varnish is a web application accelerator platform, which caches content for the sake of quicker response times. It’s sometimes called a caching HTTP reverse proxy too and it interacts between a web server and a browser. When a site visitor accesses a certain web page, the content is requested by the web browser, and then the web server handles this browser request and returns the requested info. If Varnish is activated for a site, it will cache its pages on the very first visit and in case the user accesses a cached page once again, the information will be delivered by the accelerator platform instead of the server. The boosted speed is a result of the much faster response time that the Varnish platform offers as compared with any server software. Of course, this does not mean that the website visitors will keep seeing the exact same content again and again, as any change on any of the pages is reflected in the content that the Varnish platform stores in its system memory.
Varnish in Web Hosting
If you host your websites under a web hosting account with our company, you will be able to add Varnish with several clicks through your hosting Control Panel. The caching platform is available as an optional upgrade with all our web hosting packages and you can select how many sites will use it and the total amount of system memory that will be used for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of memory and they’re not directly tied to each other, so you can choose whether you want lots of memory for a single large website or less memory for multiple smaller ones. You can unlock the full potential of the Varnish caching platform if the sites use a dedicated IP. Using the Control Panel, you can swiftly start/restart/discontinue an instance, delete the cached data independently for each website which employs Varnish or see an exhaustive system log file.
Varnish in Semi-dedicated Servers
All our semi-dedicated hosting plans include Varnish by default, so you can make full use of the website accelerator tool and optimize the load speed of any website that you host on our platform. You’ll get 64 MB of memory dedicated to Varnish at no additional cost and you can enable an instance with no more than a few mouse clicks through the Hepsia Control Panel, which comes with the semi-dedicated server packages. In case you need more memory, the latter is available in increments of 32 MB in the Control Panel’s Upgrades section and it will be available to you momentarily. You can also add more instances as a separate upgrade, so you can choose if lots of data will be cached for one website or whether the available memory will be used by several websites. Hepsia will permit you to reboot or to discontinue any instance, to check the system log associated with it or to delete the cached content using single-click controls. To take full advantage of Varnish, you can set a dedicated IP for the Internet sites that will use it.
Varnish in Dedicated Servers
If you order a dedicated server with the Hepsia hosting Control Panel, you will get Varnish at no additional charge and you will exert complete control over it via a rather time and effort saving interface – you’ll be able to start, to disable or to restart an instance, to see an elaborate log, to clear the cached content for any website and much more. Varnish will have several gigabytes of memory at its disposal, so even if you’ve got busy websites with a lot of visitors, you will notice the tremendously better website loading speeds and the reduced load on the dedicated machine. This will become a fact shortly after you begin using the Varnish platform, since it will need a certain amount of time to cache the pages that visitors request. You can make the most of the platform’s potential if the Internet sites that are using it use also a dedicated IP address, but due to the fact that your dedicated server includes several IP addresses by default, you won’t need to pay anything on top of the monthly fee for the machine itself.
