varnish cache logoVarnish is a cache, which means its role is to store and remember what a web application serves to the user the first time the content is accessed. Then it can serve the same content again for subsequent requests without asking the web application again.

It can be used to serve static content, such as images, scripts, or stylesheets, because Varnish is blazingly fast and copes with traffic much better than Apache does. It can also be used to cache quasi-static content; that is, content that is generated dynamically by the application (using the database and taking a considerable amount of time to prepare), but that stays unchanged for a period of time, making the content suitable for caching.

Put the following code at default.vcl
