Varnish In Action
ThijsFeryn
Having trouble scaling your Drupal site? Is that new marketing campaign killing your performance? Give Varnish a try.
Varnish is a reverse proxy that serves cached pages to your visitors instead of hitting the backend servers all the time. Cache is stored in RAM and there's a domain specific language that allows you to hook into your caching logic.
If you respect the rules and use the tools, Varnish will make your Drupal site bullet proof!
