Expires and Cache-Control stripped by varnish?

[Lars Jørgensen]

Hi,

Another one that I'm trying to work out at the moment. I have enabled mod_expires in Apache and set a 24 hour expiration on css. When I request a page directly from the backend, a CSS object looks like this:

Date: Wed, 18 Nov 2009 12:57:50 GMT
Server: Apache/2.2.3 (Debian) PHP/5.2.0-8+etch13
Connection: Keep-Alive
Keep-Alive: timeout=15
Etag: "da8e2c-e663-6c305b40"
Expires: Thu, 19 Nov 2009 12:57:50 GMT
Cache-Control: max-age=86400

The same object through Varnish:

Date: Wed, 18 Nov 2009 12:56:24 GMT
Via: 1.1 varnish
X-Varnish: 71655288
Last-Modified: Mon, 22 Jun 2009 10:34:45 GMT
Connection: keep-alive

I do get "304 Not Modified" on the object, but shouldn't I get the Expires and Cache-Control headers too?
