Dirk,

The example at http://varnish-cache.org/wiki/VCLExampleIgnoreCacheHeadersFromBackend should work fine.

In vcl_fetch, pop:

  set obj.ttl = 7200s;

and everything will be cached for 2hrs.

If that doesn't work, then can you post the full VCL you're using. We'll take a look, and update the website if necessary.

Hi all,

I am just trying to get familiar with varnish. I installed the latest
version 2.1.0 and with the minimal config it works as intended:

backend default {
    .host = "backend.example.com";
    .port = "80";
}

But the back-end sends an expires-header of "0", thus varnish tries to
fetch the item again from the back-end for every client requesting it.
So I need a simple rule that tells varnish to just cache every object
for say 2h, regardless what the back-end says. I just have to prevent
varnish to ask the back-end at every request.

Unfortunately the config language is not entirely self-explaining. and
most expamples on the web won't work (too old?).
Can anyone help me?
