Drupal 7.x & Varnish 3.x

Thu Jun 30 18:41:30 CEST 2011

Has anyone succeeded in getting Varnish 3.x and Drupal 7.x up & running?

Since Varnish 3 the info at 
https://www.varnish-cache.org/trac/wiki/VarnishAndDrupal
is outdated.

Below is the content of my default.vcl:

I can start Varnish (3.0) but it seems that Varnish isn't caching.

1) In Firebug: I only see one Varnish timestamp instead of two (so 
varnish isn't serving from cache)
(f.e. X-Varnish    453348501)

2) When I check with 'varnishlog -b' and refresh my Drupal pages, I see 
that Varnish still makes requests to the web backend instead of serving 
from cache.

Any ideas what's missing in my default.vcl to get Varnish 3.0 up & 
running with Drupal 7?
