Accelerate your Drupal/Pressflow site using Varnish

The primary reason for switching to Pressflow is to use an HTTP accelerator such as Varnish
Apache Configuration
Adjust your Apache configuration to server the Drupal site on port 8080. Edit your Apache conf file and add:

Listen 8080
NameVirtualHost *:8080

Restart Apache and make sure you can access your site on that port.

Varnish Configuration
Rather than change the default Varnish conf file, we'll create one just for Drupal:/usr/local/etc/varnish/drupal.vcl with Fourkitchens' basic configuration for Varnish 3.x and Drupal 7.

Drupal configuration
Edit your site's settings.php file and add your proxy to the $conf array, keeping any other settings that are there:

$conf = array(
    'reverse_proxy' => TRUE,
    'reverse_proxy_addresses' => array(
      '127.0.0.1', // Varnish web proxy
    ),
  );

Enable Drupal's page cache in admin/settings/performance and set the Caching Mode to External and Page Cache Maximum Age to an appropriate value (anything over 0).

Testing Varnish
You can test that Varnish is serving a cached page or not with:

curl -I http://yoururl.com
