Try these combinations of headers, comment from cache_util.c:

     * We now want to check if our cached data is still fresh. This depends
     * on a few things, in this order:
     * - RFC2616 14.9.4 End to end reload, Cache-Control: no-cache. no-cache in
     * either the request or the cached response means that we must
     * revalidate the request unconditionally, overriding any expiration
     * mechanism. It's equivalent to max-age=0,must-revalidate.
