You'll want something like:
sub vcl_fetch {
unset obj.http.Expires;
unset obj.http.Cache-Control;
set obj.ttl = 60m; // cache for 60 minutes within Varnish
set obj.http.Cache-Control = "public, max-age=2678400"; // cache for 31
days at User end
deliver;
}
However, depending on exactly what you want to cache for who and for how
long (do you want to cache things for people with cookies? do you really
want to cache a 1Gb .avi file within Varnish? etc), the configuration
can get a bit complex.

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?
