Seems like you have something else weird going on. The config used on www.apache.org is ExpiresActive On ExpiresDefault A86400 And yet I get updated (non-zero) cache-control headers on 304 responses:telnet www.apache.org 80Trying 192.87.106.226... Connected to www.apache.org. Escape character is '^]'. GET / HTTP/1.1 Host: www.apache.org If-Modified-Since: Thu, 01 Jun 2006 14:07:19 GMT HTTP/1.1 304 Not Modified Date: Tue, 06 Jun 2006 14:31:19 GMT Server: Apache/2.2.0 (Unix) mod_ssl/2.2.0 OpenSSL/0.9.7g ETag: "20122-331e-4152a2fa513c0" Expires: Wed, 07 Jun 2006 14:31:19 GMT Cache-Control: max-age=86400 So it looks like you have something else in your config that is resetting your cache-control headers. Joshua.
Ok, there are two things going on here, one of which I'll hang my head in shame for :-(
Firstly, the correct Cache-Control header is sent for the initial 200 response on these files - so what would prevent it from being sent only on 304 responses?
Secondly, the /Cache-Control max-age=0/ header I mentioned earlier is in the REQUEST header, not the server's response header! Seems I can't read properly!
To clarify, these are the request and response headers for an initial request for an image and then a subsequent request where the image is cached:
