Varnish is a high performance HTTP cache. The first stable version of Varnish was launched in 2006 for the Norwegian newspaper Verdens Gang. The product’s architect is Poul-Henning Kamp of Denmark.

Used to improve the performance of high traffic websites, Varnish also includes load distribution functionalities and can be used to test the availability of servers producing web content. Varnish is used by Facebook, for example. Varnish stores a portion of its data in virtual memory. The tool is configured via VCL (Varnish Configuration Language) files; this enables the definition of extremely detailed management rules. Lastly, Varnish partially supports ESI (Edge Side Includes) tags.

Varnish is distributed under the BSD License.

“ Mise en place sur plusieurs site e commerce tournant sous Magento. La performance du temps de réponse à été clairement attendu. Avant 1.2s je suis passer à 33ms. ”

“ Après l'avoir mis en place sur plusieurs projets, c'est l'outil idéal pour accélérer un site. L'installation sur une plateforme Debian/linux est ultra simple. La configuration fournie par défaut est "ready to run" pour la majorité des site de contenus. Attention cependant aux site à forte personnalisation qui vont demander une configuration plus fine. Heureusement la syntaxe de configuration permet de gérer finement ce genre de problèmes. ”

“ Solution très puissante qui permet de bâtir des plateformes hautes performances dont celle de Facebook. Trouver des ressources est de plus en plus facile mais cela nécessite une grosse expertise. ”
