cause it was politely asked by the browser "please send me a new
version if element has been updated since my last request". a 304 is
the answer to a conditional request.

also i don't really see how the metatags went into clear.gif. i'd try
to use mod_header to send real http headers to that effect and not the
metatag pseudo headers.

btw. does index.php get cached too?
