I used to have a problem of controlling flash elements on my sites.. On one site we have 6 different flash flv movies that are all the same size and are in the same position on the page. But only 1 is displayed at a time based on what the user wants to watch. So the selected flash movie needs to have the highest stacking order/zIndex.

If you remove the Last-Modified and ETag header, you will totally eliminate If-Modified-Since and If-None-Match requests and their 304 Not Modified Responses.
By removing the ETag header, you disable caches and browsers from being able to validate files, so they are forced to rely on your Cache-Control and Expires header.
A first-time visitor to your page will make several HTTP requests to download all your sites files, but using the Expires header you make those files cacheable. This avoids unnecessary HTTP requests on subsequent page views.

Verify your sites.
